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.
• Flexible Options for RS-232 and RS-422/485
Operation In One Package
• Simultaneous 2Tx/2Rx RS-232 and Half-Duplex
RS-485 Transceiver Operation (MAX3162E)
• Pin-Programmable As Either 2Tx/2Rx RS-232 or
Half/Full RS-485 Transceiver (MAX3160E,
MAX3161E)
The MAX3160E/MAX3161E/MAX3162E feature
enhanced electrostatic discharge (ESD) protection. All
of the transmitter outputs and receiver inputs are pro-
tected to 15ꢀk using the ꢁuman ꢂody Model.
• Integrated Protection Increases Robustness
• High 15kꢀ ESD HꢁM per ꢂEDEꢃ ꢂS-001-2012
• Transmitters and Receivers Protected Against
Wiring Faults
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 +3k to +5.5k 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 250ꢀbps. 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.
• True Fail-Safe Receiver Prevents False Transition
on Receiver Input Short or Open
• Short-ꢃircuit Protection Over the Entire ꢃommon-
Mode ꢀoltage Range
• Thermal Protection from Excessive Power
Dissipation
• Slew Rate Limiting Minimizes EM and Reduces
ꢃable Reflections
• Integrated ꢃharge Pump ꢃircuitry Saves ꢁoard
Space
• Eliminates the Need for a ꢁipolar 12ꢀ Supply
• Enables Single Supply Operation From +3ꢀ to
+5.5ꢀ ꢀoltage Supply
The MAX3160E/MAX3162E offer a flow-through pin-
out that facilitates board layout. The MAX3160E/
MAX3161E/MAX3162E are available in tiny SSOP pacꢀ-
ages and operate up to -40°C to +85°C temperature
ranges.
• 1µA Shutdown Supply ꢃurrent Saves Power
• Allows Up To 256 Transceivers on the ꢁus
