The MAX3311EEUB+ is a low-power, 5V EIA/TIA-232-compatible Transceiver. 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. This transceiver require only three 0.1μF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels. It features a 1μA shutdown mode. In shutdown the device turns off the charge pump, pulls V- to ground and the transmitter output is disabled.
