描述 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 Ohm), guaranteed to match within 2 Ohm between channels and to remain flat over the analog signal range (4 Ohm 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.
