The DS1691A/DS3691 are low power Schottky TTL line
drivers 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
circuit protection. A mode control input provides a choice of
operation either as 4 single-ended line drivers or 2 differential
line drivers. A rise time control pin allows the use of an
external capacitor to slow the rise time for suppression of
near end crosstalk to other receivers in the cable. Rise time
capacitors are primarily intended for waveshaping output
signals in the single-ended driver mode. Multipoint applications
in differential mode with waveshaping capacitors is not
allowed.
