DS1691A/DS3691
(RS-422/RS-423) Line Drivers with TRI-STATE Outputs
General Description
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.
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.
