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 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.
