EL4342ILZA-T7S2490

Overview

The EL4342ILZA-T7S2490 is a triple multiplex amplifier video switch IC manufactured by Renesas Electronics, formerly Intersil. It operates on a single 5 V supply or dual supplies within the -40°C to +85°C industrial temperature range. The device utilizes a QFN-EP-32 surface-mount package and features a 500 MHz bandwidth for high-speed signal routing. This component is classified as a Video Switch IC under the EL4342 series and is currently designated as an End-of-Life product with no active distribution.

Feature Summary

• Triple multiplexing capability for routing multiple video signals
• High-speed operation suitable for professional video applications
• Industrial temperature rating for reliable performance in varied environments

Applications

• Professional video switching systems
• Video surveillance infrastructure
• Broadcast equipment signal routing

Procurement Notes

This component is officially discontinued and listed as End-of-Life (EOL). No new units are available from authorized distributors. Verification of authenticity is critical when sourcing remaining stock from third-party suppliers. Buyers must confirm the specific suffix T7S2490 matches their design requirements, as legacy components may have limited traceability or warranty support.

Selection Notes

Engineers should evaluate alternative modern video switches due to the discontinuation status. Verify that the QFN-EP-32 package footprint and pinout compatibility exist for any replacement strategy. Ensure the selected substitute supports the required 500 MHz bandwidth and 5 V operating voltage to maintain system performance without redesigning the power or signal paths.

Part Context

The EL4342 belongs to the Intersil/Renesas family of high-performance video switches designed for demanding analog signal processing tasks. These devices were engineered to provide low distortion and high isolation between channels. The ILZA suffix indicates the specific commercial/industrial grade variant with the QFN-EP-32 packaging, distinguishing it from other package options in the broader EL4342 series.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific EOL component.
