TI TRS3232ECD

The TRS3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit, with pin-to-pin (serial port connection pins, including GND) ±15kV IEC ESD protection. The device complies with TIA/EIA-232-F requirements and provides an electrical interface between asynchronous communication controllers and serial port connectors. The charge pump and four small external capacitors support single-supply operation from 3V to 5.5V. These devices operate at data signaling rates up to 250kbps with a maximum driver output slew rate of 30V/μs.
