+3.0V to +5.5V / 1A / RS-232/RS-485/422 Multiprotocol Transceivers
General DescriptionThe 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 trans-
mitter output stage and an on-board dual charge pump
to allow RS-232 and RS-485/422 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 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 tempera-
ture ranges.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
