EL4340IU-T7

Overview

The EL4340IU-T7 is a video amplifier featuring three independent 2:1 multiplexer-amplifier circuits in a 24-pin QSOP package. It operates with a bandwidth of 500 MHz and a slew rate of 870 V/µs. The device draws 30 mA supply current and delivers 135 mA output current per channel. It functions at unity gain, designed for high-speed video signal routing.

Feature Summary

• Integrates triple 2:1 multiplexers suitable for RGB signal paths
• Maintains internally set unity gain configuration
• Provides high slew rates and wide bandwidth for video switching applications

Applications

• RGB video signal multiplexing
• Video switching systems
• High-speed video routing

Procurement Notes

Verify the specific suffix T7 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as documentation varies by source. Ensure the 24-QSOP footprint matches the target PCB design. Cross-reference the manufacturer part number to avoid confusion with similar Intersil or Renesas variants.

Selection Notes

Select this component for designs requiring integrated multiplexing without external gain resistors. The fixed unity gain simplifies circuit layout compared to programmable amplifiers. Evaluate the 500 MHz bandwidth against the highest frequency video signals in the application to ensure minimal distortion.

Part Context

This part belongs to the EL4340 family of video amplifiers from Renesas Electronics. These devices are engineered for fixed-gain multiplexing tasks. The series supports various video standards through its high-speed performance characteristics.

Replacement Considerations

Check the EL4342 datasheet for dual-channel alternatives if fewer channels are required. Verify pin compatibility before substituting with other video mux amplifiers.
