MAX3160CAP+

MAX3160CAP+ is a RS-232/RS-485/422 multiprotocol transceiver for point-of-sales equipment. The MAX3160 is programmable +3 to +5.5V RS-232/RS-485/422 multiprotocol transceivers. The MAX3160 is pin programmable as a 2TX/2RX RS-232 interface or a single RS-485/422 transceiver. All devices incorporate a proprietary low-dropout transmitter output stage and an on-board dual charge pump to allow RS-232 and RS-485/422 compliant performance from a +3 to +5.5V supply. These devices also feature pin-selectable transmitter slew rates for both RS-232 and RS-485/422 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-485/422 mode and up to 1Mbps in RS-232 mode. The MAX3160 offers a flow-through pinout that facilitates board layout.

• Integrated protection increases robustness - thermal protection from excessive power dissipation
• Integrated charge-pump circuitry saves board space
• 1μA shutdown supply current saves power
• Allows up to 256 transceivers on the bus
