STS700
Multifunction
Telecommunications Switch
The STS700 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 SOIC package. Its small outline and low height make it ideal for use in PCMCIA applications where multi-
function devices help reduce cost and board space.
