TRS3232 (正在供货) 具有 +/-15kV ESD 保护的 3V 至 5.5V 多通道 RS-232 线路驱动器/接收器



  • TRS3253E  -  This device has a higher data rate, an extended Vcc range (1.8V) and a 3-5 channel configuration.
  • TRSF3232  -  This device has a higher data rate.


The TRS3232 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 one
3-V to 5.5-V supply. The devices operate at data-signaling rates up to 250 kbps and a maximum of 30-V/µs driver-output slew rate.


  • RS-232 Bus-Terminal ESD Protection Exceeds
    ±15 kV Using Human-Body Model (HBM)
  • Meets or Exceeds the Requirements of
    TIA/EIA-232-F and ITU V.28 Standards
  • Operates With 3-V to 5.5-V VCC Supply
  • Operates up to 250 kbps
  • Two Drivers and Two Receivers
  • Low Supply Current: 300-µA Typical
  • External Capacitors: 4 × 0.1 µF
  • Accepts 5-V Logic Input With 3.3-V Supply
  • Alternative High-Speed Terminal-Compatible
    Devices (1 Mbps)
    • SN65C3232 (–40°C to 85°C)
    • SN75C3232 (0°C to 70°C)
