MAX9391EHJ

Overview

The MAX9391EHJ is a dual 2x2 crosspoint switch manufactured by Analog Devices Inc./Maxim Integrated. It supports input signal formats including CML, LVCMOS, LVDS, LVPECL, and LVTTL, converting them to LVDS outputs. The device operates on a single 3.3V supply voltage within a range of 3V to 3.6V. It functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a compact 32-pin TQFP package with dimensions of 5mm x 5mm.

Feature Summary

• Supports multiple input logic levels including CML, LVDS, LVPECL, LVTTL, and LVCMOS
• Converts various input signals to differential LVDS output format
• Configurable as a dual 2x2 crosspoint switch for flexible routing

Applications

• Signal routing in communication systems
• Logic level translation between different interface standards
• Data distribution networks requiring LVDS conversion

Procurement Notes

Verify the specific suffix 'EHJ' against official Analog Devices documentation to confirm pinout and package details. Confirm RoHS compliance status through current manufacturer certificates. Check for obsolescence notices or lifecycle changes directly from the supplier before finalizing procurement plans.

Selection Notes

Select this component when interfacing mixed-signal environments requiring translation from single-ended or differential inputs to LVDS. Ensure the design accommodates the 32-TQFP footprint. Verify that the system power supply remains stable within the 3V to 3.6V operating range for optimal performance.
