Description

The MAX3160E/MAX3161E/MAX3162E are programma-ble RS-232/RS-485/RS-422 multiprotocol transceivers.The MAX3160E/MAX3161E are pin programmable as a 2Tx/2Rx RS-232 interface or a single RS-485/RS-422 transceiver. The MAX3162E is configured as a 2Tx/2RxRS-232 interface, and a single RS-485/RS-422 trans-ceiver simultaneously.

The MAX3160E/MAX3161E/MAX3162E feature enhanced electrostatic discharge (ESD) protection. All of the trans-
mitter outputs and receiver inputs are protected to ±15kV using the Human Body Model.All devices incorporate a proprietary low-dropout trans-
mitter output stage, and an on-board dual charge pumpto allow RS-232- and RS-485-/RS-422-compliant perfor-mance 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 RS-232 and RS-485/RS-422 modes. Slewrate 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 MAX3160E/MAX3161E/MAX3162E
feature a 10nA shutdown mode, short-circuit limiting, and thermal shutdown circuitry to protect against excessive power dissipation.

The MAX3160E/MAX3162E offer a flow-through pin-out that facilitates board layout. The MAX3160E/MAX3161E/MAX3162E are available in tiny SSOP pack-ages and operate over the commercial and extendedtemperature ranges.
