Specifications

Front-end

  • Maxim Integrated MAX3232CSE+ true RS-232 full duplex transceivers 3.0V to 5.5V, low-power:
    • It has 2 receivers and 2 drivers.
    • For Integrated ESD Protection:  ±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V, Up to 1Mbps, True RS-232 transceivers.
    • The RS-232 transmitter guarantees a 120kbps data rate with worst-case loads of 3 kΩ in parallel with 1000pF.
    • The output stage is turned off (high impedance) when the device is in shutdown
      mode. When the power is off, the MAX3232 permits the outputs to bedriven up to ±12V.
