The AD4C333 is composed of two isolated relay; one normally open and one normally closed. Each relay has a bi-directional, single-pole, single-throw contact.

The SP541-X is a single-pole, single-throw, normally open multipurpose DC solid-state relay.It is designed to replace electromechanical relays in critical applications that require fast switching,a high load current rating and solid state relisbility.

The SDD400 consists of a Photo Darlington transistor optically coupled to a light emitting diode. Optical coupling between the input LED and output Photo Darlington allows for high isolation levels while maintaining low-level DC signal control capability.

The S210 is a single-pole, double-throw, normally open, SCR output device. The circuits are composed of one LED on the input side which activates an optically coupled IC on the output-controlling the firing angle of two back-to-back SCRs.

Isolation amplifiers are used in a wide variety of applications, including telecommunications, industrial, instrumentation and medical systems. The function of an isolation amplifier is to preserve or amplify a signal across a barrier of galvanic isolation.

The AD8C211-L is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists two integrated circuits, each driving a pair of rugged source-to-source enhancement type DMOS transistors-optically coupled to a light emitting diode.

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. It ultra-miniature package and low height make it ideal for use in PCMCIA applications where multi-function devices help reduce cost and board space.

The AD4C311 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists two integrated circuits, each driving a pair of rugged source-to-source enhancement type DMOS transistors.

The SP646 is a bi-directional, single-pole, single-throw, normally open multipurpose relay. The circuit is composed of one LED on the input side which activates an optically coupled IC on the output-controlling the firing angle of two back-to-back SCRs.
