개요
Description
The SN65ALS180DR is a Texas Instruments RS-485/RS-422 differential line transceiver (driver + receiver) in an 8-pin package. It enables two-wire, half‑duplex bus communication with separate driver enable (DE) and receiver enable (RE) controls and a tri‑state output. The receiver offers a fail‑safe RO output when the bus is idle or open. It is designed for multi-point industrial and building-automation networks and supports single-supply operation with differential A/B signaling. Data rates align with RS-485 standards (typically up to about 10 Mbps on suitable buses). The DR suffix denotes a specific packaging/variant from TI. For exact electrical specs (voltage range, data rate, propagation delay, enable timing, and pinout), consult the TI datasheet.
