AD42211
2 Form A
Solid State Relay
DESCRIPTION
The AD42211 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 of two integrated circuits, each driving a pair of
rugged source-to-source enhancement type DMOS transistors. Both integrated circuits are optically coupled to one light emitting diode,
which controls both switches. The output MOS transistors are protected with free-wheeling diodes that can handle up to 1.5A of inrush
current, making the relay ideal for switching lamps and highly inductive loads.
