DS7830/DS8830

Dual Differential Line Driver

General Description

The DS7830/DS8830 is a dual differential line driver that

also performs the dual four-input NAND or dual four-input

AND function.

TTL (Transistor-Transistor-Logic) multiple emitter inputs al-

low this line driver to interface with standard TTL systems.

The differential outputs are balanced and are designed to

drive long lengths of coaxial cable, strip line, or twisted pair

transmission lines with characteristic impedances of 50

Ω to

500

Ω. The differential feature of the output eliminates

troublesome ground-loop errors normally associated with

single-wire transmissions.

Features

n Single 5V power supply

n Diode protected outputs for termination of positive and

negative voltage transients

n Diode protected inputs to prevent line ringing

n High speed
