The MAX3161EAG+ is a RS-232/RS-485/422 Multiprotocol Transceiver for point-of-sales equipment. The MAX3161 is pin programmable as a 2Tx/2Rx RS-232 interface or a single RS-485/RS-422 transceiver. All devices incorporate a proprietary low-dropout transmitter output stage and an on-board dual charge pump to allow RS-232- and RS-485-/RS-422-compliant performance from a +3 to +5.5V supply. These devices also feature pin-selectable transmitter slew rates for RS-232 and RS-485/RS-422 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 these devices to transmit at data rates up to 10Mbps in RS-485/RS-422 mode and up to 1Mbps in RS-232 mode.
