Features and Benefits

  • ESD Protection for RS-232-Compatible I/O Pins ±15kV—Human Body Model
  • 1µA Low-Power Shutdown (MAX3311E)
  • Active-low INVALID Output (MAX3313E)
  • Receiver Active in Shutdown (MAX3311E)
  • Single Transceiver (1Tx/1Rx) in 10-Pin µMAX Package

Product Details

The MAX3311E/MAX3313E are low-power, 5V EIA/TIA-232-compatible transceivers. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model, making these devices ideal for applications where more robust transceivers are required.

Both devices have one transmitter and one receiver. The transmitters have a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V supply with a single inverting charge pump. These transceivers require only three 0.1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels.

The MAX3311E features a 1µA shutdown mode. In shutdown the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled. The MAX3313E features an active-low INVALID output that asserts high when an active RS-232 cable signal is connected, signaling to the host that a peripheral is connected to the communication port.
