TRS202E中文资料具有 +/-9V 输出和 +/-15kV IEC-ESD 保护的 5V 双通道 120kbps RS-232 线路驱动器/接收器数据手册TI规格书

描述 Description

The TRS202E device consists of two line drivers, two line receivers, and a dual charge-pump circuit. TRS202E has IEC61000-4-2 (Level 4) 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 device operates at data signaling rates up to 120 kbit/s and a maximum of 30-V/µs driver output slew rate.
