description
The SN55173, SN65173, and SN75173 are
monolithic quadruple differential line receivers
with 3-state outputs. They are designed to meet
the requirements of TIA/EIA-422-B,
TIA/EIA-423-B, TIA/EIA-485-A, and several ITU
recommendations. The standards are for
balanced multipoint bus transmission at rates up
to 10 megabits per second. The four receivers
share two OR enable inputs, one active when
high, the other active when low. These devices
feature high input impedance, input hysteresis for
increased noise immunity, and input sensitivity of
± 200 mV over a common-mode input voltage
range of – 12 V to 12 V. Fail-safe design specifies
that if the inputs are open circuited, the outputs are
always high. The SN65173 and SN75173 are
designed for optimum performance when used
with the SN75172 or SN75174 quad differential
line drivers.
