TIA/EIA-422-B, TIA/EIA-423-B, and

TIA/EIA-485-A and ITU Recommendations

V.10, V.11, X.26, and X.27

on Long Bus Lines in Noisy Environments

– 12 V to 12 V

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.

The SN55173 is characterized over the full military temperature range of – 55

°C to 125°C. The SN65173 is

characterized for operation from –40

°C to 85°C. The SN75173 is characterized for operation from 0°C to 70°C.
