DS96173/DS96175
RS-485/RS-422 Quad Differential Line Receivers
General Description
The DS96173 and DS96175 are high speed quad differential
line receivers designed to meet EIA Standard RS-485. The
devices have TRI-STATE® outputs and are optimized for bal-
anced multipoint data bus transmission at rates up to 10
Mbps. The receivers feature high input impedance, input
hysteresis for increased noise immunity, and input sensitivity
of 200 mV over a common mode input voltage range of −7V
to +12V. The receivers are therefore suitable for multipoint
applications in noisy environments. The DS96173 features
an active high and active low Enable, common to all four re-
ceivers. The DS96175 features separate active high Enables
for each receiver pair. Compatible RS-485 drivers, transceiv-
ers, and repeaters are also offered to provide optimum bus
performance. The respective device types are DS96172,
DS96174, DS96176 and DS96177.
