Description
The AD4C742 is composed of two distinct 1 Form B
(normally closed) relays in one compact 8 pin DIP package.
Each relay consists of an AlGaAs LED optically coupled to
a Photo Diode Array, driving a pair of rugged source-tosource
depletion type DMOS transistors. The AD4C742
has an extremely low on resistance (500mΩ TYP) and high
load current capability (600mA per channel), giving the
device unparalleled performance for a normally closed
relay.

Features
 Low Input Control Current (2.5mA TYP)
 600mA Maximum Continuous Load Current (per Channel)
 Low On Resistance (500mΩ TYP)
 High Isolation Voltage (up to 5kVRMS)
 Long Life / High Reliability
 RoHS / Pb-Free / REACH Compliant

Applications
 Meter Reading Systems
 Multiplexers
 Data Acquisition
 Medical Equipment
 Battery Monitoring
 Home / Safety Security Systems
