MAX3162ECAI+

Overview

The MAX3162ECAI+ is a multiprotocol transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin SSOP package. It operates from a +3.0V to +5.5V supply and features simultaneous 2Tx/2Rx RS-232 and half-duplex RS-485/RS-422 interfaces. The device includes an on-board dual charge pump for single-supply operation. Electrical specifications include ±15kV ESD protection per Human Body Model, a shutdown current of 1µA, and data rates up to 1Mbps for RS-232 and 10Mbps for RS-485/RS-422. Operating temperature range is -40°C to +85°C.

Feature Summary

• Simultaneous 2Tx/2Rx RS-232 and half-duplex RS-485/RS-422 transceiver operation
• Integrated dual charge pump eliminates the need for bipolar ±12V supplies
• Pin-selectable transmitter slew rates minimize EMI and reduce cable reflections
• High ±15kV ESD protection on all transmitter outputs and receiver inputs

Applications

• Point-of-Sales Equipment
• Industrial Controls
• RS-232 to RS-485 Interface Converters
• Security Systems

Procurement Notes

Verify the specific suffix 'EAI+' against official documentation to confirm the extended temperature range (-40°C to +85°C) and lead-free packaging status. Confirm pinout compatibility with the 28-pin SSOP footprint during integration. Ensure that the ordering information matches the exact part number variant required for the intended application environment.

Selection Notes

Select this component when simultaneous RS-232 and RS-485 communication is required within a single integrated circuit. The MAX3162E is distinct from the MAX3160E and MAX3161E due to its separate digital I/O ports and dedicated driver/receiver pairs for both protocols. Verify that the board layout supports the flow-through pinout configuration to facilitate efficient routing.

Part Context

The MAX3162E belongs to the MAX3160/MAX3161/MAX3162 family of low-power, multiprotocol transceivers. While the MAX3160E shares I/O ports between protocols and the MAX3161E shares logic lines, the MAX3162E provides fully independent interfaces. This makes it suitable for protocol translation applications where two distinct buses must operate concurrently without signal contention.
