MC3488A_06 Datasheet, PDF (1/6 Pages) ON Semiconductor – Dual EIA−423/EIA−232D Line Driver

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.
