MAX3162ECAI

Overview

The MAX3162ECAI is a multiprotocol transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for RS-232 and RS-485/RS-422 communication interfaces. It integrates two drivers and two receivers within a single SSOP-28 package. The device operates on a supply voltage ranging from +3.0V to +5.5V and supports data rates up to 10 Mb/s in RS-485/RS-422 mode. It features 15 kV ESD protection on all pins and draws only 125 uA of operating supply current. The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Supports simultaneous 2TX/2RX RS-232 and half-duplex RS-485 transceiver operation
• Integrates proprietary low-dropout transmitter output stage with onboard dual charge pump
• Features pin-selectable transmitter slew rates to minimize EMI and reduce reflections

Applications

• Point-of-sales equipment
• Industrial controls
• RS-232 to RS-485 interface converters

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to commercial variants. Confirm the 'AI' designation corresponds to the SSOP-28 package type. Ensure compatibility with existing board layouts due to the flow-through pinout design. Cross-reference datasheet revisions to confirm pin definitions remain consistent with previous generations.

Selection Notes

Select this component when both RS-232 and RS-485/RS-422 protocols are required in a single system. The integrated charge pump eliminates external components, simplifying design. Verify that the 10 Mb/s data rate meets application requirements. Ensure the 125 uA quiescent current aligns with power budget constraints for portable or battery-operated devices.

Part Context

This part belongs to the MAX3160/MAX3161/MAX3162 family of multiprotocol transceivers. Unlike the MAX3160 and MAX3161, which are pin-programmable as either RS-232 or RS-485/422, the MAX3162 uniquely combines both interfaces simultaneously. This distinguishes it from standard single-protocol transceivers found in similar industrial interface categories.
