MAX3160CAP+

MAX3160CAP+ is a RS-232/RS-485/422 multiprotocol transceiver for point-of-sales equipment. It is a programmable +3 to +5.5V RS-232/RS-485/422 multiprotocol transceiver. The MAX3160 is pin programmable as a 2TX/2RX RS-232 interface or a single RS-485/422 transceiver. The device incorporates 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. This device also features 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. Applications include point-of-sales equipment, industrial controls, RS-232 to RS-485 interface converters, peripherals, networking.

• Integrated protection increases robustness, transmitter and receiver protected against wiring faults
• True fail-safe receiver prevents false transition on receiver input short or open
• Short-circuit protection over the entire common mode voltage range
• Thermal protection from excessive power dissipation
• Slew rate limiting minimizes EM and reduces cable reflections
• Integrated charge-pump circuitry saves board space
• VCC standby current is 1.2mA typ at no load, RS485/active-low RS232=GND
• VCC shutdown current is 1µA typ at active-low SHDN=GND, receiver inputs open or grounded
• 20 SSOP package
• Temperature rating range from 0°C to +70°C
