19-0391; Rev 0; 5/95 Low-Voltage, Quad, SPDT, CMOS Analog Switch ____________________________Features The MAX394 is a precision, low-voltage, quad, singlepole/double-throw (SPDT) analog switch. The four independent switches operate with bipolar supplies ranging from ±2.7V to ±8V, or with a single supply of +2.7V to +15V. The MAX394 offers low on-resistance (less than 35Ω), guaranteed to match within 2Ω between channels and to remain flat over the analog signal range (∆4Ω max). It also offers break-before-make switching (10ns typical), with turn-off times less than 75ns and turn-on times less than 130ns. The MAX394 is ideal for portable operation since quiescent current runs less than 1µA with all inputs high or low. ♦ Low On-Resistance, < 17Ω Typical (35Ω max) ♦ Guaranteed Matched On-Resistance Between Channels, < 2Ω ♦ Guaranteed Flat On-Resistance over Analog Signal Range, ∆4Ω Max ♦ Guaranteed Charge Injection < 10pC ♦ Guaranteed Off-Channel Leakage < 2.5nA at +85°C ♦ ESD Guaranteed > 2000V per Method 3015.7 ♦ Single-Supply Operation (+2.7V to +15V) Bipolar-Supply Operation (±2.7V to ±8V) ♦ TTL/CMOS-Logic Compatibility ♦ Rail-to-Rail Analog Signal Handling Capability ♦ Pin Compatible with MAX333, MAX333A This monolithic, quad switch is fabricated with Maxim’s low voltage silicon-gate process. Design improvements guarantee extremely low charge injection (10pC), low power consumption (10µW), and electrostatic discharge (ESD) greater than 2000V. Logic inputs are TTL and CMOS compatible and guaranteed over a +0.8V to +2.4V range for supply voltages up to +8V. When supplies exceed +8V, the inputs are typically +0.8V to +4V. Logic inputs and switched analog signals can range anywhere between the supply voltages without damage. ________________________Applications Test Equipment Communications Systems PBX, PABX Heads-Up Displays Portable Instruments Audio Signal Routing Set-Top Boxes ______________Ordering Information PART TEMP.

In either case, analog signals ranging from V+ to V- can be switched. The Typical Operating Characteristics graphs show the typical on-resistance variation with analog signal and supply voltage. The usual on-resistance temperature coefficient is 0.5%/°C (typ). Power-Supply Sequencing and Overvoltage Protection Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+, followed by V- (when using split supplies) before applying analog signals or logic inputs, especially if the analog or logic signals are not currentlimited. If this sequencing is not possible and if the analog or logic inputs are not current-limited to less than Figure 1. Overvoltage Protection Using Blocking Diodes 30mA, add a single diode (D1) for single-supply operation (Figure 1). If using dual supplies or if the analog signal can dip below ground in single-supply operation, add two small signal diodes (D1, D2), as shown in Figure 1. Adding protection diodes reduces the analog signal range to a diode drop above V- for D2. Leakage is not affected by adding the diodes. On-resistance increases by a small amount at low supply voltages. Maximum supply voltage (V- to V+) must not exceed 17V. Adding diodes D1 and D2 also protects against some overvoltage situations. With the circuit of Figure 1, if the supply voltage is below the absolute maximum rating and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. For example, with ±5V supplies, analog signals up to ±8.5V will not damage the circuit of Figure 1. If only a single fault signal is present, the fault voltage can go to +12V or -12V without damage. _______________________________________________________________________________________ 9 MAX394 Low-Voltage, Quad, SPDT, CMOS Analog Switch ______________________________________________Test Circuits/Timing Diagrams t R < 20ns t F < 20ns 3V 50% V IN 50% 0V +10V 50% 50% 0V 50% -10V NO_ 300Ω IN_ t OPEN MAX394 GND V+ LOGIC INPUT 50% +15V t OFF t ON SWITCH OUTPUT COM_ -10V t OFF V COM NC_ +10V t ON t OPEN V- -15V (REPEAT TEST FOR IN2, IN3, AND IN4.)
