Description
The PS394 is a precision, low-voltage, quad, single-pole/doublethrow (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 PS394 offers low ON-resistance (less than 35 ohms), guaranteed to match within 6 ohms between channels and to remain flat over the analog signal range (10 ohms 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 PS394 is ideal for portable operation since quiescent current runs less than 1µA with all inputs high or low. This monolithic, quad switch is fabricated using Pericom's 17V silicon-gate process. Design improvements guarantee extremely low charge injection and low power consumption (10µW). Logic Inputs are TTL and CMOS compatible and guaranteed over a +0.8V to +2.4V range. Logic inputs and switched analog signals can range anywhere between the supply voltages without damage.
