The SDD450 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 S211 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.

The M211 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay in a miniature 4-pin small outline package. It is designed to replace electromechanical relays in general purpose switching applications.

The AD6C541 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 TD3043 consists of a single input LED optically coupled to a zero-volt crossing triac driver. The TD3063 provides high input-to-output isolation and is designed to drive high-powered triacs. Typical include interfacing logic level control signals to equipment powered from 110Vac and 220Vac lines.

The AD4C212 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 SP540-X is a single-pole, single-throw, normally open multipurpose DC solid-state relay and is designed to replace electromechanical relays in critical applications that require fast switching and solid state reliability.

The SDD1600 combines four independent optocouplers in a 16 pin DIP/SMD package. Each of the four optocoupler circuits is composed of an input LED optically-coupled to a Photo Darlington Transistor--allowing for high isolation levels while maintaining low-level DC signal control capability. The SDD1600 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
