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
