SN75173N Datasheet | Texas Instruments

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 remendations. 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 m V over a mon-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. 1Y 3 2 1 20 19 4A G5 17 4Y NC 6 16 NC 2Y 7 15 G 2A 8 14 3Y 9 10 11 12 13 2B GND NC 3B 3A - No internal connection THE SN55173 IS NOT REMENDED FOR NEW DESIGNS.
