The Analog Devices ADM207ARSZ is a full‑function RS‑232 transceiver IC designed for reliable serial communication between logic‑level circuits and RS‑232 interfaces. It integrates 5 drivers and 3 receivers in a single device, making it ideal for implementing multi‑signal RS‑232 ports with minimal external components. Operating from a single 5 V power supply, the ADM207ARSZ includes an internal charge pump that generates the required ±9 V RS‑232 output levels without needing dual supplies. It supports data rates up to approximately 120 kbps, providing robust connectivity for UART/serial links in industrial and consumer equipment. Encased in a compact 24‑lead SSOP (Shrink Small Outline Package), this transceiver is well‑suited for surface‑mount PCB designs.
