MAX4892EETX+T

Analog Switches - Special Purpose Overview

The MAX4892EETX+T is an analog switch IC designed for high-speed differential switching in Gigabit Ethernet (10/100/1000 Base-T) and LVDS/LVPECL applications. It features eight bidirectional channels within a 36-pin TQFN package, providing enhanced ±15kV ESD protection per MIL-STD-883 Method 3015. The device operates on a single +3.0V to +3.6V supply with a maximum quiescent current of 450µA. Key electrical parameters include a typical on-resistance of 4Ω, ultra-low on-capacitance of 8pF, and a -3dB bandwidth of 650MHz. It includes three built-in LED switches for docking station indicator routing.

Analog Switches - Special Purpose Feature Summary

• Enhanced electrostatic discharge protection rated at ±15kV Human Body Model
• Ultra-low insertion loss and wide bandwidth suitable for Gigabit Ethernet interfaces
• Integrated LED switching capability for laptop computer and docking station use

Analog Switches - Special Purpose Applications

• Notebooks and docking stations
• Servers and routers with Ethernet interfaces
• Board-level redundancy protection
• SONET/SDH signal routing
• LVDS and LVPECL switching

Analog Switches - Special Purpose Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before finalizing design specifications. Confirm that the lead-free package designation (+) aligns with environmental compliance requirements such as RoHS standards. Ensure the 36-pin TQFN footprint matches the target PCB layout constraints.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring robust ESD protection for external Ethernet connections. The integrated LED switches simplify docking station designs by allowing indicator signals to be routed alongside data lines. Verify that the operating voltage range of 3.0V to 3.6V matches the system power supply architecture.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4890E/MAX4892E family of 1000 Base-T LAN switches. It serves as a pin-for-pin equivalent to the non-E versions but offers superior ESD protection. The MAX4892E specifically adds LED switching functionality compared to the MAX4890E, making it distinct for applications requiring signal routing to docking station indicators.

Analog Switches - Special Purpose Replacement Considerations

The MAX4890EETJ+ is a compatible alternative within the same family, offering similar performance but without the LED switching feature and housed in a 32-pin package.
