February1996 MM78C29 MM88C29Quad Single-Ended Line Driver
MM78C30 MM88C30Dual Differential Line Driver
General Description
The MM78C30 MM88C30is a dual differential line driver
that also performs the dual four-input NAND or dual four-in-
put AND function The absence of a clamp diode to V CC in
the input protection circuitry of the MM78C30 MM88C30al-
lows a CMOS user to interface systems operating at differ-
ent voltage levels Thus a CMOS digital signal source can
operate at a V CC voltage greater than the V CC voltage of
the MM78C30line driver The differential output of the
MM78C30 MM88C30eliminates ground-loop errors
The MM78C29 MM88C29is a non-inverting single-wire
transmission line driver Since the output ON resistance is a
low20X typ the device can be used to drive lamps relays
solenoids and clock lines besides driving data lines
