TRS3232

具有 +/-15kV ESD 保护的 3V 至 5.5V 多通道 RS-232 线路驱动器/接收器

The device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal-to-terminal serial-port connection terminals, including GND. The device meets the requirements of A/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from one

3-V to 5.5-V supply. The devices operate at data-signaling rates up to 250 kbps and a maximum of 30-V/µs driver-output slew rate.
