TRS3232E

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 IEC ESD protection pin to pin serial-port connection pins, 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 a single 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.
