TRS208中文资料具有 +/-9V 输出和 +/-15kV ESD 保护的 5V 四通道 120kbps RS-232 线路驱动器/接收器数据手册TI规格书

描述 Description

The TRS208 device consists of four line drivers, four line receivers, and a dual charge-pump circuit with ±15-kV HBM ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/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 5-V supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/µs driver output slew rate.
