3V 到 5.5V 多通道 RS-232 线路驱动器和接收器

 

备选器件推荐

  • TRS3232E  -  The device has the SAME FUNCTIONALITY/PINOUT as the compared device but includes enhanced IEC61000-4-2 ESD protection. TI recommends the TRS3232E in new designs
  • TRS3232  - 器件与被比较器件在功能和参数上完全等效。 

描述

The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal to terminal (serial-port connection terminals, 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 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
