MAX3746HETE#TG16

Overview

The MAX3746HETE#TG16 is a single-channel limiting amplifier IC designed for Ethernet applications. It operates within a supply voltage range of 2.97 V to 3.63 V and draws a typical operating current of 35 mA. The device supports data rates from 622 Mbps to 3.2 Gbps and functions reliably across an extended temperature range of -40°C to +85°C. Packaged in a 16-TQFN (3x3 mm) surface-mount format with an exposed pad, it dissipates up to 1.4 W of power.

Feature Summary

• Provides signal amplification for high-speed serial communication links
• Supports data transmission rates up to 3.2 Gbps
• Engineered specifically for Ethernet interface applications

Applications

• Ethernet receiver front-end conditioning
• High-speed serial data link signal restoration
• Optical transceiver module input stages

Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Verification of availability should focus on surplus or secondary market sources rather than direct factory allocation. Buyers must confirm the authenticity of the part number suffix and ensure compliance with relevant environmental regulations such as RoHS status before acquisition.

Selection Notes

Designers requiring this specific performance profile should evaluate successor devices within the Analog Devices portfolio that offer updated manufacturing support. Selection criteria must prioritize compatibility with existing board layouts, particularly the 16-TQFN footprint and pinout configuration. Engineers should verify that alternative components maintain equivalent gain characteristics and bandwidth specifications for the target Ethernet standard.

Part Context

The MAX3746 series represents a family of limiting amplifiers optimized for optical and copper-based Ethernet interfaces. This specific variant integrates the HETE package designation, indicating a thermal-enhanced thin quad flat no-lead construction. It serves as a critical interface component between photodetectors or line drivers and subsequent digital processing stages in network hardware.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status.
