ИС интерфейса RS-422/RS-485 MAX3162EAI+

Многопротокольный приемопередатчик RS-232/RS485/422 , +3.0В до +5.5В, 1мкА, SSOP-28

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
