NJM2264D

Video Processing Overview

The NJM2264D is a 3-input, 1-output video superimposer with an integrated 75Ω driver circuit manufactured by Nisshinbo Micro Devices Inc. It operates on a single supply voltage ranging from 4.75V to 13V and features a wide operating frequency range of 10MHz for 2VP-P input signals. The device includes an internal sink chip clamp function at the VIN1 input to adjust DC levels, while VIN2 and VIN3 provide transistor open base control for luminance signals. It achieves a crosstalk performance of 70dB at 4.43MHz and utilizes bipolar technology within a DIP-8 package.

Video Processing Feature Summary

• Provides dedicated inputs for luminance signal control via transistor open base

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 intended solely for existing customers currently in use. Production will cease in the near term, and availability is limited to a specific time frame. It is not approved for new project designs. Engineers must verify current stock status and lead times directly with the manufacturer or authorized distributors before initiating any procurement actions.

Video Processing Selection Notes

Designers should consider this part only for maintenance or replacement of legacy systems where the specific 3-input switching and 75Ω output characteristics are required. Due to its discontinuation status, alternative components with similar electrical specifications and pin compatibility should be evaluated for any new hardware development to ensure long-term supply chain stability.

Video Processing Part Context

The NJM2264 belongs to the NJM2264 series, which encompasses variants such as the NJM2264L and NJM2264M. These devices share the same core functionality as a 3-input video superimposer but differ in their physical packaging configurations. The D suffix specifically denotes the DIP-8 package format used for through-hole mounting applications.
