Low-Voltage, Quad, SPDT, CMOS Analog Switch
_______________General Description
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 35), guaranteed to match within 2 between channels and to remain flat over the analog signal range (4 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 1A with all inputs high or low. 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 (10W), 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.

Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode 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: 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: RON = RON(max) - RON(min). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal range. Note 5: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature. Note 6: See Figure 6. Off-isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch. Note 7: Between any two switches. See Figure 3. Note 8: Leakage testing at single supply is guaranteed by testing with dual supplies.

__________Applications Information
Operation with Supply Voltages Other than 5V
The MAX394 switch operates with 2.7V to 8V bipolar supplies and a +2.7V to +15V single supply. 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).
Figure 1. Overvoltage Protection Using Blocking Diodes
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
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.
