+5V, RS-232 Transceivers with 0.1F External Capacitors
General Description
The MAX200-MAX209/MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication interfaces where Q12V supplies are not available. On-board charge pumps convert the +5V input to the Q10V needed for RS-232 output levels. The MAX201 and MAX209 operate from +5V and +12V, respectively, and contain a +12V to -12V charge-pump voltage converter. The MAX200-MAX209/MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a 20kbps data rate. The drivers maintain the Q5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification. The 5FW shutdown mode of the MAX200, MAX205, MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing the ring indicator (RI) to be monitored easily using only 75FW power. The MAX211 and MAX213 are available in a 28-pin, wide small-outline (SO) package and a 28-pin shrink smalloutline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now available in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components and are recommended for applications with limited circuit board space.

Detailed Description
The MAX200-MAX209/MAX211/MAX213 consist of three sections: charge-pump voltage converters, drivers (transmitters), and receivers. Each section is described in detail.

The +5V to Q10V conversion is performed by two charge-pump voltage converters (Figure 4). The first uses capacitor C1 to double +5V to +10V, storing +10V on the V+ output filter capacitor, C3. The second chargepump voltage converter uses capacitor C2 to invert +10V to -10V, storing -10V on the V- output filter capacitor, C4.

+5.5V
The MAX201 and MAX209 include only the V+ to Vcharge pump, and are intended for applications that have a VCC = +5V supply and a V+ supply in the +9V to +13.2V range. In shutdown mode, V+ is internally connected to VCC by a 1kI pulldown resistor and V- is internally connected to ground by a 1kI pullup resistor. When VCC = +5V, the typical driver output-voltage swing is Q8V when loaded with a nominal 5kI RS-232 receiver. The output swing is guaranteed to meet the EIA/TIA-232E and V.28 specifications, which call for Q5V minimum output levels under worst-case conditions. These include a minimum 3kI load, VCC = +4.5V, and the maximum operating temperature. The open-circuit output-voltage swing ranges from (V+ - 0.6V) to V-. Input thresholds are both CMOS and TTL compatible. The inputs of unused drivers can be left unconnected since 400kI pullup resistors to VCC are included onchip. Since all drivers invert, the pullup resistors force the outputs of unused drivers low. The input pullup resistors typically source 15A; therefore, the driver inputs should be driven high or open circuited to minimize power-supply current in shutdown mode. When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1mA, even if the transmitter output is backdriven between 0V and (VCC + 6V). Below -0.5V, the transmitter output is diode clamped to ground with a 1kI series impedance. The transmitter output is also zener clamped to approximately (VCC + 6V), with a 1kI series impedance.

The receivers convert RS-232 signals to CMOS logic output levels. Receiver outputs are inverting, maintaining compatibility with driver outputs. The guaranteed receiver input thresholds of +0.8V and +2.4V are significantly tighter than the Q3.0V threshold required by the EIA/TIA-232E specification. This allows receiver inputs to respond to TTL/CMOS logic levels and improves noise margin for RS-232 levels.
RS-232 Receivers
The MAX200-MAX209/MAX211/MAX213 guaranteed +0.8V threshold (+0.6V in shutdown for the MAX213) ensures that receivers shorted to ground have a logic 1 output. Also, the 5kI input resistance to ground ensures that a receiver with its input left open also has a logic 1 output. Receiver inputs have approximately +0.5V hysteresis. This provides clean output transitions, even with slow rise and fall time input signals with moderate amounts of noise and ringing. In shutdown, the MAX213 receivers R4 and R5 have no hysteresis.

current typically to 1A (15A for the MAX213). The time required to exit shutdown is 1ms, as shown in Figure 5. All receivers except R4 and R5 on the MAX213 are put into a high-impedance state in shutdown mode. The MAX213's R4 and R5 receivers still function in shutdown mode. These two receivers are useful for monitoring external activity while maintaining minimal power consumption. The enable control is used to put the receiver outputs into a high-impedance state, so that the receivers can be connected directly to a three-state bus. It has no effect on the RS-232 drivers or on the charge pumps. During normal operation, the MAX213's receiver propagation delay is typically 1Fs. When entering shutdown with receivers active, R4 and R5 are not valid until 80Fs after SHDN is driven low. In shutdown mode, propagation delays increase to 4Fs for a high-to-low or a low-tohigh transition. When exiting shutdown, all receiver outputs are invalid until the charge pumps reach nominal values (< 2ms when using 0.1FF capacitors).

Applications Information
The type of capacitor used is not critical for proper operation. Ceramic capacitors are suggested. To ensure proper RS-232 signal levels over temperature when using 0.1FF capacitors, make sure the capacitance value does not degrade excessively as the temperature varies. If in doubt, use capacitors with a larger nominal value. Also observe the capacitors' ESR value over temperature, since it influences the amount of ripple on V+ and V-. To reduce the output impedance at V+ and V-, use larger capacitors (up to 10FF). If polarized capacitors are used, obey the polarities shown in Figure 1 and the pin configurations. Each transmitter is designed to drive a single receiver. Transmitters can be paralleled to drive multiple receivers.
Capacitor Selection
Figure 5 shows two driver outputs exiting shutdown. As they become active, the two driver outputs go to opposite RS-232 levels (one driver input is high, the other is low). Each driver is loaded with 3kI in parallel with 2500pF. The driver outputs display no ringing or undesirable transients as they come out of shutdown. In applications that are sensitive to power-supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitors. A small amount of power can be drawn from V+ and V-, although this reduces noise margins. If at power-up the V+ supply rises after the VCC supply, place a diode (e.g., 1N914) in series with the V+ supply.
