STS750
Multifunction
Telecommunications Switch
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.
