MAX394

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 35½), guaranteed to match within 2½ between channels and to remain flat over the analog signal range (Æ4½ 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 MAX394 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 of MAX394 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.
