General 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/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 transmitter outputs and receiver inputs are pro-
tected 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
performance from a +3V to +5.5V supply. 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/MAX3162E offer a flow-through pin-
out that facilitates board layout. The MAX3160E/
MAX3161E/MAX3162E are available in tiny SSOP pack-
ages and operate up to -40°C to +85°C 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.
