EL4331CSZ

Overview

The EL4331CSZ is a dual very high speed 2:1 Multiplexer-Amplifier manufactured by Elantec Semiconductor. It features an internally fixed gain of 2, facilitating the driving of back-terminated cables without external components. The device switches simultaneously from A to B inputs via a TTL/CMOS compatible common control pin. Key electrical parameters include a 300 MHz bandwidth and a slew rate exceeding 650V/µs.

Feature Summary

• Dual channel architecture with simultaneous switching capability
• Internally fixed gain of 2 for simplified cable driving
• High-speed performance with 300 MHz bandwidth

Applications

• Component video multiplexing
• Pixel switching
• RGB multiplexing
• HDTV processing

Procurement Notes

Verify the manufacturer origin, as Intersil and Renesas acquired Elantec's assets. Confirm the package type matches the SOIC-16 specification. Ensure the datasheet aligns with the specific suffix requirements for temperature range and lead-free compliance before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution is required for high-frequency signal routing. The internal gain of 2 reduces external component count compared to discrete amplifier configurations. Verify that the TTL/CMOS control logic compatibility meets the system interface requirements.

Part Context

This part belongs to the EL433x series of mux-amplifiers designed for video applications. It shares functional similarities with the EL4332 but differs in channel count. The series is characterized by high bandwidth and fast switching speeds suitable for professional video equipment.

Replacement Considerations

Check for direct equivalents such as the EL4332 for dual-channel needs or other triple-channel variants if more inputs are required. Verify pinout compatibility with existing board layouts before substitution.
