STMicroelectronics ST3237E RS-232 Transceiver Datasheet
The ST3237E is a high data-rate RS-232 transceiver designed for operation with a 3V to 5.5V supply. It features enhanced electrostatic discharge (ESD) protection, rated at +15KV for the Human Body Model and +8KV for IEC 1000-4-2 contact discharge. The device utilizes a proprietary low-dropout transmitter output stage and a dual charge pump to achieve true RS-232 performance from low-voltage supplies.
