MM74C908 MM74C918 Dual CMOS 30V Relay Driver
General Description
Features
The MM74C908 and MM74C918 are general purpose dual
high voltage drivers each capable of sourcing a minimum of
250 mA at VOUT e VCC b 3V and TJ e 65 C
The MM74C908 and MM74C918 consist of two CMOS
NAND gates driving 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
b30V across the device These CMOS drivers are useful in
interfacing normal CMOS voltage levels to driving relays
regulators lamps etc
Y Wide supply voltage range
Y High noise immunity
Y Low output ‘‘ON’’ resistance
Y High voltage
Y High current
