| STS750 Multifunction Telecommunications Switch DESCRIPTION The STS750 is a multi-function telecommunications relay. It combines a 1 Form A solid state relay, phototransistor, Darlington transistor and a bridge rectifier in a 16-pin small outline package. Its ultra-miniature package and low height make it ideal for use in PCMCIA applications where multi-function devices help reduce cost and board space.
