Texas Instruments SN55LBC173-HIREL Quadruple Low-Power Differential Line Receiver SN55LBC173MKGD1

The SN55LBC173-HIREL is a quadruple low-power differential line receiver designed to meet EIA standards RS-422-A, RS-423-A, RS-485, and CCITT V.11. It features a low power consumption of 20 mA maximum and is optimized for balanced multipoint bus transmission, supporting data rates exceeding 10 million bits per second. The device includes high input impedance and input hysteresis for improved noise immunity, with an input sensitivity of ¬±200 mV across a common-mode input voltage range of 12 V to -7 V. Its fail-safe design ensures that the output remains high when inputs are open-circuited. The SN55LBC173 is built using Texas Instruments' proprietary LinBiCMOS technology, which enhances its robustness and performance in noisy environments. The operating temperature range is from -55¬8C to 125¬8C, making it suitable for a variety of applications.
