Texas Instruments SN65LBC176A Differential Bus Transceivers SN65LBC176AQD

The SN65LBC176A is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. It supports signaling rates up to 30 Mbps and is compatible with ANSI standard TIA/EIA-485-A and ISO 8482:1987(E). The device features low skew, thermal shutdown protection, and a common mode voltage range of ,Äì7 V to 12 V, making it suitable for noisy environments and long bus lines. The transceiver operates from a single 5-V power supply and includes a 3-state differential line driver and a differential input line receiver. It has low disabled supply current requirements, with a maximum of 700 ¬µA, and incorporates driver positive and negative current limiting. The receiver input sensitivity is ¬±200 mV with a typical hysteresis of 50 mV, ensuring reliable operation. The open-circuit failsafe design enhances performance in various applications. The SN65LBC176A is available in multiple package options, including SOIC and PDIP, and is suitable for high-reliability automotive applications.
