General Description

The 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 V

protection circuitry of the MM88C30 allows a CMOS user to
interface systems operating at different voltage levels.
Thus, a CMOS digital signal sou rce can operate at a V

voltage greater than the VCC voltage of the MM88C30 line
driver. The differential output of the MM88C30 eliminates

ground-loop errors.

in the input

CC

The MM88C29 is a non -inverting single-wire t ransmission
line driver. Since the output ON resistance is a low 20Ω
typ., the device can be used to drive lamps, relays, sole­noids, and clock lines, besides driving data lines.

Features

■ Wide supply voltage range: 3V to 15V

■ High noise immunity: 0.45 V

■ Low output ON resistance: 20Ω (typ.)
