† 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.


Description

The SN55LBC173 is a monolithic quadruple differential line receiver with 3-state outputs and is designed to meet the requirements of the EIA standards RS-422-A, RS-423-A, RS-485, and CCITT V.11. SN55LBC173 is 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 if the inputs are open circuited, the output is always high. The SN55LBC173 is designed using the Texas Instruments proprietary LinBiCMOSEtechnology that provides low power consumption, high switching speeds, and robustness.

This device offers optimum performance when used with the SN55LBC172M quadruple line driver. The SN55LBC173 is available in the 16-pin CDIP (J), the 16-pin CPAK (W), or the 20-pin LCCC (FK) packages. The SN55LBC173 is characterized over the military temperature range of 55°C to 125°C.
