MAX3160ECAP-MAX3160EEAP
+5kV ESD-Protected, +3.0V to +5.5V, 10nA, RS-232/RS-485/RS-422 Multiprotocol Transceivers
General DescriptionThe 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/2Rx
RS-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 pump
to 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 receiv-
er 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. 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/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 extended
temperature 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.
