MAX3311/MAX3313 19-1901 Rev 0 2/01 460kbps, 1A Supply Current, RS-232-Compatible Transceivers in MAX General Description Features The MAX3311/MAX3313 are low-power, +5V EIA/TIA- 1A Low-Power Shutdown (MAX3311) 232-compatible transceivers. Both devices have one INVALID Output (MAX3313) transmitter and one receiver. The transceivers have a proprietary low-dropout transmitter output stage Receiver Active in Shutdown (MAX3311) enabling RS-232-compatible operation from a +5V sup- Single Transceiver (1Tx/1Rx) in 10-Pin MAX ply with a single inverting charge pump. These devices require only three 0.1F capacitors and will run at data RS-232-Compatible Operation rates up to 460kbps while maintaining RS-232-compati- ble output levels. The MAX3311 features a 1A shutdown mode. In shut- down the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled. The MAX3313 features an INVALID output that asserts high when an active RS-232 cable signal is connected, sig- naling to the host that a peripheral is connected to the communication port.
