MAX3160

Product Summary

The MAX3160 is a RS-232/RS-485/422 Multiprotocol Transceiver. The MAX3160 is programmable 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. The MAX3160 is configured as a 2Tx/2Rx RS-232 interface and a single RS-485/422 transceiver simultaneously. The receivers feature true fail-safe circuitry that guarantees a logichigh 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 feature a 1μA shutdown mode, and short-circuit limiting and thermal shutdown circuitry to protect against excessive power dissipation. The MAX3160 offer a flow-through pinout that facilitates board layout. The MAX3160 is available in tiny SSOP packages and operate over the commercial and extended temperature ranges. The applications of the MAX3160 include Point-of-Sales Equipment, Industrial Controls, RS-232 to RS-485, Interface Converters, Peripherals and Networking.
