MAX3161EAG+T

Overview

The MAX3161EAG+T is a multiprotocol transceiver in a 24-pin SSOP package, operating from -40°C to +85°C. It supports RS-232 and RS-485/RS-422 interfaces with a single +3V to +5.5V supply. The device features pin-selectable data rates up to 1Mbps for RS-232 and 10Mbps for RS-485/RS-422. Shutdown current is 1µA. It includes integrated dual charge pumps, fail-safe receivers, and thermal protection.

Feature Summary

• Pin-programmable configuration allows operation as either a 2TX/2RX RS-232 interface or a single RS-485/RS-422 transceiver.
• Integrated dual charge pump circuitry eliminates the need for external bipolar ±12V power supplies.
• Fail-safe receiver design guarantees a logic-high output when inputs are open or shorted.
• Pin-selectable slew-rate limiting minimizes electromagnetic interference and reduces cable reflections.

Applications

• Point-of-Sales Equipment
• Industrial Controls
• Networking

Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape-and-reel packaging format. Confirm the 'E' designation indicates the extended temperature range of -40°C to +85°C. Ensure the component is lead-free and RoHS compliant as indicated by the '+' suffix before finalizing procurement specifications.

Selection Notes

Select this model over the MAX3160 if separate transmitter outputs and receiver inputs are required for both protocols. This part is optimized for multiplexing a single UART across two distinct interface buses. Verify that the 24-pin SSOP package dimensions fit the target board layout constraints.

Part Context

This component belongs to the MAX3160/MAX3161/MAX3162 family of programmable multiprotocol transceivers. While the MAX3160 shares I/O pins and the MAX3162 operates simultaneously, the MAX3161 provides separate driver and receiver paths for each protocol within a single 24-pin SSOP package.
