NJM2266D

Video Processing Overview

The NJM2266D is a 3-input, 1-output video superimposer with an internal 6dB amplifier. It operates on a supply voltage of 4.75V to 13V and consumes up to 21mA. The device features a sink-chip clamp function at VIN1 for DC level adjustment and luminance signal control at VIN2/VIN3. It provides 65dB crosstalk suppression at 4.43MHz and utilizes bipolar technology in an 8-DIP package.

Video Processing Feature Summary

• Integrates a 3-to-1 video switch with a built-in 6dB amplifier circuit
• Includes a sink-chip clamp function for DC level adjustment
• Provides dedicated inputs for luminance signal control

Video Processing Applications

• Video Cassette Recorders (VCR)
• Video Cameras
• Audio-Visual Televisions (AV-TV)
• Video Disc Players

Video Processing Procurement Notes

This component is designated as a discontinued product by the manufacturer. Production will cease in the near term, and availability is restricted to existing customers with a limited timeframe. It is not recommended for new project designs. Verify current stock status and lead times directly with authorized distributors or sales offices before initiating procurement.

Video Processing Selection Notes

Select this part only if designing for legacy systems requiring a 3-input video switch with integrated amplification. Ensure the design accommodates the specific clamp input requirements, including necessary pull-down resistors. Consider alternative modern video switches if new production is planned due to the discontinuation status.

Video Processing Part Context

The NJM2266 series includes variants such as the NJM2266L and NJM2266M, offering different package options like DMP8 and SIP8 alongside the DIP8 version. All variants share the same core functionality as a high-performance video switch operated by a single 4.75V supply voltage using bipolar technology.
