The MAX3227EIDBR is an RS-232 interface IC manufactured by Texas Instruments. It is a single-channel line driver/receiver made with 3-5.5V operating voltage. It has five pins dedicated to data, two pins dedicated to leds, one pin for VCC, and one for ground. Its integrated circuitry ensures that it is robust to system noise and supports speeds up to 250kbps. The IC supports full-duplex communication for data, enabling it to work in applications where simultaneous data transmission and receiving are required. It is designed to meet ESD requirements of 15kV HBM, 1.5kV CDM, and 1000V MM. Additionally, applications such as PC cards, PDAs, modems, and sensors benefit from its low power consumption feature of 5uA in shutdown mode.
