Overview
The SN75LBC175A, produced by Texas Instruments, is a quadruple differential line receiver designed for high-speed multipoint data transmission applications. It is optimized for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 (Euro RS-485) standards. These devices are suitable for balanced multipoint bus communication at data rates exceeding 50 million bits per second and can operate over a wide range of positive and negative common-mode input voltages. The SN75LBC175A is characterized for operation over the temperature range of 0°C to 70°C and is built using LinBiCMOS™ technology, which facilitates low power consumption and inherent robustness.
