MAX3311E/MAX3313E 19-1910 Rev 0 1/01 15kV ESD-Protected, 460kbps, 1A, RS-232-Compatible Transceivers in MAX General Description Features The MAX3311E/MAX3313E are low-power, 5V EIA/TIA- ESD Protection for RS-232-Compatible I/O Pins 232-compatible transceivers. All transmitter outputs 15kVHuman Body Model and receiver inputs are protected to 15kV using the Human Body Model, making these devices ideal for 1A Low-Power Shutdown (MAX3311E) applications where more robust transceivers are required. INVALID Output (MAX3313E) Both devices have one transmitter and one receiver. Receiver Active in Shutdown (MAX3311E) The transmitters have a proprietary low-dropout trans- mitter output stage enabling RS-232-compatible opera- Single Transceiver (1Tx/1Rx) in 10-Pin MAX tion from a +5V supply with a single inverting charge pump. These transceivers require only three 0.1F Package capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels. The MAX3311E features a 1A shutdown mode. In shutdown the device turns off the charge pump, pulls Ordering Information V- to ground, and the transmitter output is disabled. The MAX3313E features an INVALID output that asserts PART TEMP.
