MM78C29MM88C29 Quad Single-Ended Line Driver

MM78C30MM88C30 Dual Differential Line Driver

General Description

The MM78C30MM88C30 is a dual differential line driver

that also performs the dual four-input NAND or dual four-in-

the input protection circuitry of the MM78C30MM88C30 al-

lows a CMOS user to interface systems operating at differ-

ent voltage levels Thus a CMOS digital signal source can

the MM78C30 line driver The differential output of the

MM78C30MM88C30 eliminates ground-loop errors

The MM78C29MM88C29 is a non-inverting single-wire

transmission line driver Since the output ON resistance is a

low 20X typ the device can be used to drive lamps relays

solenoids and clock lines besides driving data lines
