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 V

CC

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 V

CC

voltage greater than the VCCvoltage 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

Wide supply voltage range 3V to 15V

Y

*AC Parameters are guaranteed by DC correlated testing.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’ they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation.

Note 2: Capacitance is guaranteed by periodic testing.

Note 3: C

PD

determines the no load AC power consumption of any CMOS device. For complete explanation see 54C/74C Family Characteristics application note
