Product Details

The SW201 contains four independent, single-pole (SPST) analog switches, which may be independently digitally controlled. Each SW201 switch is normally closed (NC), when the corresponding input is zero.

The judicious combination of bipolar and FET devices in a single monolithic IC results in a product with performance characteristics and ruggedness that are superior to those of a similar circuit fabricated using CMOS technology.

Increased reliability is complemented by excellent electrical specifications. Potential error sources are reduced by minimizing "ON" resistance and controlling leakage currents at high temperatures. The switching FET exhibits minimal RON variation over a 20V analog signal range and with power supply voltage changes. Operation from a single positive power supply voltage is possible. With V+=36V, V-=0V, the analog signal range will extend from ground to +32V.

The PNP logic inputs are TTL and CMOS compatible. Logic input currents are at micro-ampere levels which improves circuit fan in.
