MAX9394EHJ+T

Overview

The MAX9394EHJ+T is a high-speed analog and digital crosspoint IC featuring a 2:1 multiplexer and a 1:2 demultiplexer with loopback. It operates on a single 3.0V to 3.6V supply within an extended temperature range of -40°C to +85°C. The device supports LVDS, HSTL, LVPECL, and CML signaling standards through dedicated fail-safe circuitry. It provides guaranteed 1.5GHz operation with less than 87ps channel-to-channel skew and ultra-low jitter performance.

Feature Summary

• Simultaneous independent loopback control for both multiplexer and demultiplexer channels
• High-level input fail-safe detection for GND-referenced differential inputs
• Low-level input fail-safe detection for VCC-referenced differential inputs
• LVCMOS/LVTTL logic inputs for internal connection control

Applications

• High-Speed Telecom/Datacom Equipment
• Central Office Backplane Clock Distribution
• DSLAM
• Protection Switching
• Fault-Tolerant Systems

Procurement Notes

Verify the specific suffix EHJ+T against the manufacturer's current datasheet to confirm lead-free status and package dimensions. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure the ordering code matches the required temperature range and pin configuration before finalizing procurement.

Selection Notes

Select this component when simultaneous signal redundancy switching and loopback testing are required in high-speed data links. The MAX9394 variant is suitable for GND-referenced inputs like LVDS and HSTL, while the MAX9395 handles VCC-referenced signals such as LVPECL and CML. Ensure the design accommodates the 32-pin TQFP footprint and 3.3V power domain.

Part Context

This part belongs to the MAX9390 series of analog and digital crosspoint switches manufactured by Analog Devices Inc./Maxim Integrated. It is designed for communication and networking applications requiring precise signal routing. The device integrates multiplexing and demultiplexing functions into a single compact package to reduce board space and complexity.
