NJM2533D

Video Processing Overview

The NJM2533D is a video switch IC designed for VCR and TV applications. It features two bias-type inputs and one buffer-type output within an 8-DIP package. The device operates on a supply voltage ranging from +4.75V to +13V with a maximum operating current of 3.7mA. Key electrical specifications include a crosstalk level of -70dB at 4.3MHz, a voltage gain of 0dB, and a frequency characteristic of ±1.0dB up to 10MHz. The component utilizes bipolar technology and supports an operating temperature range of -40°C to +85°C.

Video Processing Feature Summary

• Integrates two bias-type inputs and one buffer-type output for signal routing
• Provides high isolation with -70dB crosstalk performance
• Operates on a wide single supply voltage range from +4.75V to +13V
• Utilizes robust bipolar technology for stable switching

Video Processing Applications

• Video switching in VCR systems
• Signal routing in television sets
• General consumer video equipment requiring 2-input 1-output switching

Video Processing Procurement Notes

Verify the specific suffix 'D' confirms the DIP-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation as requirements may vary by production batch. Ensure the design accommodates the specified operating temperature range of -40°C to +85°C. Check for any Not Recommended for New Design (NRND) notices or lifecycle updates directly from Nisshinbo Micro Devices before finalizing procurement plans.

Video Processing Selection Notes

Select this component for designs requiring a simple 2-to-1 video signal selector. The DIP-8 package facilitates through-hole mounting for prototyping or specific enclosure constraints. Consider the 3.7mA maximum current draw for power budget calculations. Verify that the input impedance and output offset voltage meet the specific requirements of the connected video sources and displays.

Video Processing Part Context

The NJM2533 belongs to a family of video switch integrated circuits manufactured by Nisshinbo Micro Devices. Variants such as NJM2533M, NJM2533V, and NJM2533L share identical internal circuitry but differ in physical packaging options including DMP-8, SSOP-8, and SIP-8. This allows designers to choose the most suitable form factor for their assembly process while maintaining consistent electrical performance across the series.

Video Processing Replacement Considerations

Direct pin-compatible replacements within the same family include NJM2533M (DMP-8), NJM2533V (SSOP-8), and NJM2533L (SIP-8). These variants offer identical electrical characteristics and functionality. Ensure the replacement package type matches the PCB footprint and mounting requirements of the existing design.
