General Description

The MM74C908 is a general purpose dual high voltage driver capable of sourcing a minimum of 250 mA at VOUT = VCC − 3V, and TJ = 65°C.

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.

Features

■ Wide supply voltage range: 3V to 18V

■ High noise immunity: 0.45 VCC (typ.)

■ Low output “ON” resistance: 8Ω (typ.)

■ High voltage: −30V

■ High current: 250 mA
