AD4C742 Datasheet, PDF (1/8 Pages) Solid State Optronic – Low Input Control Current (2.5mA TYP)

AD4C742
Dual 1 Form B
60V / 1Ω
MOSFET Output Solid State Relay
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-to-
source 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.
The AD4C742 comes standard in a compact 8 pin DIP
package making it ideal for high-density board applications.
Applications
 Meter Reading Systems
 Multiplexers
 Data Acquisition
 Medical Equipment
 Battery Monitoring
 Home / Safety Security Systems
