MM78C29 MM88C29 Quad Single-Ended Line Driver MM78C30 MM88C30 Dual Differential Line Driver
General Description
The MM78C30 MM88C30 is a dual differential line driver that also performs the dual four-input NAND or dual four-input AND function The absence of a clamp diode to VCC in the input protection circuitry of the MM78C30 MM88C30 allows a CMOS user to interface systems operating at different voltage levels Thus a CMOS digital signal source can operate at a VCC voltage greater than the VCC voltage of the MM78C30 line driver The differential output of the MM78C30 MM88C30 eliminates ground-loop errors The MM78C29 MM88C29 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

MM78C30 MM88C30 Dual Differential Line Driver
General Description
The MM78C30 MM88C30 is 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 VCC in
the input protection circuitry of the MM78C30 MM88C30 al-
lows a CMOS user to interface systems operating at differ-
ent voltage levels Thus a CMOS digital signal source can
operate at a VCC voltage greater than the VCC voltage of
the MM78C30 line driver The differential output of the
MM78C30 MM88C30 eliminates ground-loop errors
The MM78C29 MM88C29 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
