19-1393; Rev 1; 8/99 5, Quad, SPST, CMOS Analog Switches General Description The MAX4604/MAX4605/MAX4606 quad analog switches feature 5 max on-resistance. On-resistance is matched between switches to 0.5 max and is flat (0.5 max) over the specified signal range. Each switch can handle Rail-to-Rail(R) analog signals. The off-leakage current is only 2.5nA max at +85C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. These switches have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4604 has four normally closed (NC) switches, the MAX4605 has four normally open (NO) switches, and the MAX4606 has two NC and two NO switches. These switches operate from a single supply of +4.5V to +36V or from dual supplies of 4.5V to 20V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using 15V supplies or a single +12V supply. o Low On-Resistance (5 max) o Guaranteed RON Match Between Channels (0.5 max) o Guaranteed RON Flatness over Specified Signal Range (0.5 max) o Rail-to-Rail Signal Handling o Guaranteed ESD Protection > 2000V per Method 3015.7 o Single-Supply Operation: +4.5V to +36V Dual-Supply Operation: 4.5V to 20V o TTL/CMOS-Compatible Control Inputs Features MAX4604/MAX4605/MAX4606 Ordering Information PART MAX4604CSE MAX4604CPE MAX4604ESE MAX4604EPE TEMP.

Ground Logic-Supply Input Positive Analog Supply Input FUNCTION _______________________________________________________________________________________ 7 5, Quad, SPST, CMOS Analog Switches MAX4604/MAX4605/MAX4606 Applications Information Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 44V. These protection diodes are not recommended when using a single supply. switch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50 source and load connected with BNC connectors to a circuit board deemed "average;" that is, designed with isolation in mind, but not using strip-line or other special RF circuit techniques. For critical applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz. +15V D1 V+ MAX4604 MAX4605 MAX4606 * COM_ * NO_ Off-Isolation at High Frequencies In 50 systems, the high-frequency on-response of these parts extends from DC to above 100MHz with a typical loss of -2dB. When the switch is turned off, however, it behaves like a capacitor, and off isolation decreases with increasing frequency. (Above 300MHz, the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the * * VD2 -15V * INTERNAL PROTECTION DIODES Figure 1.
