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-in-
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.

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