The MAX3162ECAI+ is a ±15KV ESD protected 3V to 5.5V, 10nA, RS232/RS485/ RS422 multiprotocol transceiver in 28 pin SSOP package. It is configured as a 2 transmitter/2 receiver RS232 interface and a single half-duplex RS485/RS422 transceiver simultaneously. It features enhanced electrostatic discharge (ESD) protection. The transmitter outputs and receiver inputs are protected to ±15KV using the Human Body Model. This device incorporate a low dropout transmitter output stage and an onboard dual charge pump to allow RS232 and RS485/RS422 compliant performance from a +3V to +5.5V supply. It also feature pin selectable transmitter slew rates for RS232 and RS485/RS422 modes. Slew rate limiting minimizes EMI and reduces reflections caused by improperly terminated cables allowing error free data transmission up to 250Kbps. Disabling slew rate limiting allows this device to transmit at data rates up to 10Mbps in RS485/RS422 mode and up to 1Mbps in RS232 mode.
