The MAX3311E/MAX3313E are low-power, 5V EIA/TIA232-compatibletransceivers. All transmitter outputsand receiver inputs are protected to ±15kV using theHuman Body Model, making these devices ideal forapplications where more robust transceivers arerequired.

Both devices have one transmitter and one receiver.The transmitters have a proprietary low-dropout transmitteroutput stage enabling RS-232-compatible operationfrom a +5V supply with a single inverting chargepump.

These transceivers require only three 0.1µFcapacitors and will run at data rates up to 460kbpswhile maintaining RS-232-compatible output levels.The MAX3311E features a 1µA shutdown mode. Inshutdown the device turns off the charge pump, pullsV- to ground, and the transmitter output is disabled.

The MAX3313E features an INVALID output that assertshigh when an active RS-232 cable signal is connected,signaling to the host that a peripheral is connected tothe communication port.
