MAX3082ECSA+T

MAX3082ECSA+T is a dual RS-232 transceiver from Maxim Integrated. It provides two transmitters and two receivers, allowing TTL/CMOS logic to interface with RS-232 ports and back. The device runs on a single 3.0–5.5 V supply and includes an internal charge pump to generate the RS-232 voltage rails, so no external ± voltages are needed. It supports full-duplex serial communication at moderate speeds and is designed for low power, suitable for portable or battery-powered apps. The ECSA suffix indicates an extended (industrial) temperature range with RoHS-compliant packaging, and +T denotes Tape-and-Reel packaging for automated assembly. Typical uses include microcontroller-based serial interfaces, data loggers, and industrial controllers requiring robust RS-232 connectivity. For exact specs (data rate, voltage swings, input/output thresholds, shutdown behavior, and pinout), consult the MAX3082 datasheet.
