ST ST3243E ±15KV ESD PROTECTED 3 TO 5.5V 400KBPS RS-232 TRANSCEIVER WITH AUTO-POWERDOWN handbook(1)
The ST3243E is a low-dropout RS-232 transceiver designed for operation from a 3.0V to 5.5V supply voltage. It features enhanced electrostatic discharge (ESD) protection, rated at +15KV Human Body Model and +8KV Contact Discharge, ensuring robust performance in portable devices.
The device includes three drivers and five receivers with an integrated dual charge-pump circuit. A key feature is the auto-powerdown function, which disables driver outputs to reduce supply current to 1A when no valid signal is detected, making it ideal for battery-powered equipment.
