DS1691A/DS3691

(RS-422/RS-423) Line Drivers with TRI-STATE^®Outputs

General Description

Features

n Dual RS-422 line driver with mode pin low, or quad

RS-423 line driver with mode pin high

n TRI-STATE outputs in RS-422 mode

n Short circuit protection for both source and sink outputs

n Outputs will not clamp line with power off or in

TRI-STATE

The DS1691A/DS3691 are low power Schottky TTL line driv-

ers designed to meet the requirements of EIA standards

RS-422 and RS-423. They feature 4 buffered outputs with

high source and sink current capability with internal short cir-

cuit protection. A mode control input provides a choice of op-

eration either as 4 single-ended line drivers or 2 differential

line drivers. A rise time control pin allows the use of an exter-

nal capacitor to slow the rise time for suppression of near

end crosstalk to other receivers in the cable. Rise time ca-

pacitors are primarily intended for waveshaping output sig-

nals in the single-ended driver mode. Multipoint applications

in differential mode with waveshaping capacitors is not al-

lowed.

n 100Ω transmission line drive capability

n Low I_CCand I_EEpower consumption

RS-422: I_CC9 mA/driver typ

RS-423: I_CC4.5 mA/driver typ:

2.5 mA/driver typ

n Low current PNP inputs compatible with TTL, MOS and

CMOS

n Pin compatible with AM26LS30

With the mode select pin low, the DS1691A/DS3691 are

dual-differential line drivers with TRI-STATE outputs. They

feature 10V output common-mode range in TRI-STATE

mode and 0V output unbalance when operated with 5V

supply.
