Maxim Integrated (MAX3162EAI+) RS232/RS485/422 Multiprotocol Transceivers

Product Overview The MAX3162EAI+ is a RS-232/RS-485/422 Multiprotocol Transceiver for point-of-sales equipment. The MAX3162 is configured as a 2TX/2RX RS-232 interface and a single RS-485/422 transceiver simultaneously. 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. The MAX3162 offer 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 Applications Industrial, Automation & Process Control, Communications & Networking, Computers & Computer Peripherals Product Information Device Type: Transceiver IC Interface Type: RS232, RS422, RS485 No. of Drivers: 2Drivers No. of Receivers: 2Receivers Supply Voltage Min: 3V Supply Voltage Max: 5.5V Driver Case Style: SSOP No. of Pins: 28Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
