TCM4400EGGM TI Interface IC | RS-485 Transceiver | 3.3V, 250kbps, Half-Duplex

Product Overview

The TCM4400EGGM from Texas Instruments is a low-power, half-duplex RS-485 transceiver designed for balanced data transmission. It operates from a single 3.3V supply and features a driver output capable of delivering up to 250kbps data rate. The device is optimized for long-distance communication in noisy environments, with extended common-mode range and fail-safe receiver inputs. Housed in a compact MSOP-8 package, the TCM4400EGGM is ideal for space-constrained applications requiring robust serial communication.
