General Description
The MAX3160/MAX3161/MAX3162 are programmable RS-232/RS-485/422 multiprotocol transceivers. The MAX3160/MAX3161 are pin programmable as a 2Tx/2Rx RS-232 interface or a single RS-485/422 transceiver. 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-485/422 compliant performance from a +3V to +5.5V supply. The receivers feature true fail-safe circuitry that guarantees a logic high receiver output when the receiver inputs are open or shorted. 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/MAX3161/MAX3162 feature a 1µA shutdown mode, and short-circuit limiting and thermal shutdown circuitry to protect against excessive power dissipation. The MAX3160/MAX3162 offer a flow-through pinout that facilitates board layout. The MAX3160/MAX3161/MAX3162 are available in tiny SSOP packages and operate over the commercial and extended temperature ranges.
