SN75C3232

符合 RS-232 的 3V 至 5.5V 两通道线路驱动器/接收器

The SN65C3232 and consist of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin serial-port connection pins, including GND. These devices provide 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 1 Mbit/s and a driver output slew rate of 24 V/µs to 150 V/µs.
