description
The SN65LBC173 and SN75LBC173 are monolithic quadruple differential line receivers with 3-state outputs.
Both are designed to meet the requirements of the ANSI standards EIA/TIA-422-B, EIA/TIA-423-B, RS-485,
and ITU Recommendations V.10 and V.11. The devices are optimized for balanced multipoint bus transmission
at data rates up to and exceeding 10 million bits per second. The four receivers share two ORed enable inputs,
one active when high, the other active when low.
Each receiver features 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 –7 V. Fail-safe design ensures that
iftheinputsareopencircuited, theoutputisalwayshigh. BothdevicesaredesignedusingtheTexasInstruments
proprietary LinBiCMOS technology that provides low power consumption, high switching speeds, and
robustness.
These devices offer optimum performance when used with the SN75LBC172 or SN75LBC174 quadruple line
drivers. The SN65LBC173 and SN75LBC173 are available in the 16-pin DIP (N) and SOIC (D) packages.
The SN65LBC173 is characterized over the industrial temperature range of –40°C to 85°C. The SN75LBC173
is characterized for operation over the commercial temperature range of 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND.
2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
