SSOUSA AD4C250 Two optically isolated ssrs in compact 8 pin dip package Datasheet

AD4C250
Dual 1 Form A
Solid State Relay
DESCRIPTION
The AD4C250 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace
electromechanical relays and reed relays in special applications that call for very fast switching times. The relay consists of two integrated
circuits, each driving a pair of rugged source-to-source enhancement type DMOS transistors. Each integrated circuit is optically coupled
to a light emitting diode. The output MOS transistors are specially designed to exhibit extremely low output capacitance and leakage
current characteristics, making this device ideal for switching high frequency signals.
