SN65C3232E中文资料具有 +/-15kV IEC-ESD 保护的 3V 至 5.5V 双通道 1Mbps RS-232 线路驱动器/接收器数据手册TI规格书

描述 Description

The SN65C3232E and SN75C3232E 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 14 V/µs to 150 V/µs.
