EL4340IUZ

Overview

The EL4340IUZ is a triple, multiplexing amplifier featuring fixed unity gain and high-speed three-state outputs. It integrates triple 2:1 and 4:1 multiplexers designed for RGB signal routing. The device operates on ±5V supplies and includes a power-down mode to reduce consumption in sensitive applications. Key electrical characteristics include a 500MHz bandwidth and an ±870 V/µs slew rate. Typical supply current is 10mA per channel. The component utilizes a lead-free RoHS-compliant QSOP-24 package.

Feature Summary

• Integrates triple 2:1 and 4:1 multiplexers with internally set unity gain for RGB signal handling
• Features high-speed three-state outputs (HIZ) enabling wired connections of multiple devices
• Includes a dedicated power-down mode to disable unneeded circuitry for power-sensitive designs

Applications

• HDTV and DTV analog input circuits
• Video projector signal routing
• Computer monitor display interfaces
• Set-top box video processing
• Broadcast video equipment

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or temperature grades. Confirm that the procurement source provides the original manufacturer datasheet rather than third-party interpretations. Ensure the component meets current environmental compliance standards required for your manufacturing process. Cross-reference the part number with the latest revision history to avoid obsolete stock.

Selection Notes

Select this component when designing systems requiring simultaneous routing of multiple RGB signals through a single interface path. The integrated HIZ output state simplifies bus sharing without external tri-state buffers. Consider the ±5V operating requirement when designing the power distribution network. The low typical supply current makes it suitable for applications where thermal management and power efficiency are critical constraints.

Part Context

This device belongs to the Elantec multiplexing amplifier family, specifically engineered for high-frequency video signal switching. It addresses the need for compact, high-bandwidth signal routing in consumer electronics and broadcast infrastructure. The design eliminates the complexity of discrete multiplexer solutions by integrating three independent channels into a single package.

Replacement Considerations

The EL4340 is functionally similar to the ISL59481 and ISL59482 series from Intersil. Verify pinout compatibility and package dimensions before substitution. Check if the alternative device offers the same triple-channel configuration and HIZ functionality.
