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

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.
