MM74C908
Dual CMOS 30-Volt Relay Driver
General Description
The MM74C908 is a general purpose dual high voltage
driver capable of sourcing a minimum of 250 mA at V

The MM74C908 consists of two CMOS NAND gates driv-
ing an emitter follower Darlington output to achieve high
current drive and high voltage capabilities. In the “OFF”
state the outputs can withstand a maximum of
30V across
the device. These CMOS drivers are useful in interfacing
normal CMOS voltage levels to driving relays, regulators,
lamps, etc.
