Improved, Quad, SPST Analog Switches
General Description
Maxim's redesigned DG444/DG445 analog switches now feature on-resistance matching (4 max) between switches and guaranteed on-resistance flatness over the signal range (9 max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection (10pC max), low power consumption (35W max), and an electrostatic discharge (ESD) tolerance of 2000V (min) per Method 3015.7. The new design offers lower off-leakage current over temperature (less than 5nA at +85C). The DG444/DG445 are quad, single-pole/single-throw (SPST) analog switches. The DG444 has four normally closed switches and the DG445 has four normally open switches. Switching times are less than 250ns for tON and less than 70ns for tOFF. Operation is from a single +10V to +30V supply, or bipolar 4.5V to 20V supplies. Maxim's improved DG444/DG445 continue to be fabricated with a 44V silicon-gate process.

Note 1: Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Typical values are for design aid only, are not guaranteed, and are not subject to production testing. The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the specified analog signal range. Note 5: Leakage parameters IS(OFF), ID(OFF), ID(ON), and IS(ON) are 100% tested at the maximum rated hot temperature and guaranteed at +25C. Note 6: Off-Isolation Rejection Ratio = 20log (VD/VS), VD = output, VS = input to off switch. Note 7: Between any two switches.

ate with 4.5V to 20V bipolar supplies or with a +10V to +30V single supply; connect V- to 0V when operating with a single supply. Also, all device types can operate with unbalanced supplies such as +24V and -5V. VL must be connected to +5V to be TTL compatible, or to V+ for CMOS-logic level inputs. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)
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 may cause permanent damage to the devices. Always sequence V+ on first, followed by VL , V-, and logic inputs. If power-supply sequencing is not possible, add two small, external signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and Vshould not exceed +44V.

Applications Information
General Operation
* Switches are open when power is off. * IN, D, and S should not exceed V+ or V-, even with the power off. * Switch leakage is from each analog switch terminal to V+ or V-, not to other switch terminals.

Operation with Supply Voltages Other than 15V
Using supply voltages other than 15V will reduce the analog signal range. The DG444/DG445 switches operV-
