MM74C918 - Dual CMOS 30V Relay Driver

Download the MM74C918 datasheet PDF. This datasheet also covers the MM74C908 variant, as both devices belong to the same dual cmos 30v relay driver family and are provided as variant models within a single manufacturer datasheet.

Key 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 la.
