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. Features Y Y Y Wide supply voltage range High noise immunity Low output ON resistance 3V to 15V 0.45 VCC (typ.) 20X (typ.)
