EL4340IU-T13

Overview

The EL4340IU-T13 is a triple, fixed unity-gain multiplexing amplifier manufactured by Renesas Electronics Corporation. It features high slew rates and excellent bandwidth for video switching applications. The device includes a high impedance output state (HIZ) that enables the outputs of multiple devices to be wired together. A power-down mode (ENABLE) is included to turn off un-needed circuitry in power sensitive applications. Latch enable functionality is provided for the EL4340 variant. The component operates with ±5V supply voltage and offers a typical slew rate of ±870 V/µs with a 500MHz bandwidth.

Feature Summary

• Triple 2:1 and 4:1 multiplexers designed for RGB signal routing
• Internally set gain-of-1 configuration for fixed unity gain operation
• High speed three-state outputs allowing wired connection of multiple devices
• Power-down mode to reduce current consumption in power-sensitive applications

Applications

• HDTV/DTV analog inputs
• Video projectors
• Computer monitors
• Set-top boxes
• Security video systems

Procurement Notes

Verify the exact suffix against official documentation, as 'T13' typically indicates tape and reel packaging. Confirm RoHS compliance status through the manufacturer's datasheet or environmental declaration. Check for product discontinuation notices or end-of-life notifications from Renesas Electronics. Ensure the specific package type matches your PCB design requirements before ordering.

Selection Notes

Select this component for applications requiring high-speed video signal switching with minimal external gain-setting components. The internal unity gain simplifies circuit design compared to programmable gain amplifiers. Consider the power-down feature for battery-operated or energy-efficient systems. Verify compatibility with ±5V power supplies and ensure the HIZ output capability meets system wiring constraints.

Part Context

The EL4340 series belongs to Renesas' portfolio of high-speed video processing ICs, originally developed under the Intersil brand. These amplifiers are engineered for professional and consumer video equipment where signal integrity and switching speed are critical. The triple multiplexer architecture allows efficient handling of RGB color channels within a single compact package.

Replacement Considerations

EL4342IUZ-T13: Similar triple multiplexing amplifier but lacks latch enable functionality.
