MC3488A

Dual EIA−423/EIA−232D

Line Driver

The MC3488A dual is single−ended line driver has been designed to

satisfy the requirements of EIA standards EIA−423 and EIA−232D, as

well as CCITT X.26, X.28 and Federal Standard FIDS1030. It is

suitable for use where signal wave shaping is desired and the output

load resistance is greater than 450

W. Output slew rates are adjustable

from 1.0

ms to 100 ms by a single external resistor. Output level and

slew rate are insensitive to power supply variations. Input undershoot

diodes limit transients below ground and output current limiting is

provided in both output states.

The MC3488A has a standard 1.5 V input logic threshold for TTL or

NMOS compatibility.
