NJM2279M

Video Processing Overview

The NJM2279M is a 3-input, 2-output video switch IC designed for AV applications. It integrates a 6dB amplifier and 75Ω driver circuits, allowing direct connection to TV monitors. The device operates on dual supplies of ±4V to ±7V or single supply of +8V to +14V. Key electrical parameters include an operating current of 10.0mA to 24.6mA, voltage gain of 6.0dB to 6.8dB, and input/output crosstalk of -70dB. It features internal mute functions and utilizes bipolar technology in a DMP-14 package.

Video Processing Feature Summary

• Integrates 6dB amplifier and 75Ω driver circuitry for direct monitor connection
• Provides independent mute control for two output channels
• Supports flexible power supply configurations including dual and single rail operation

Video Processing Applications

• AV set video switching
• TV monitor signal routing
• Video signal distribution systems

Video Processing Procurement Notes

Verify the specific suffix 'M' corresponds to the DMP-14 package variant as indicated in official documentation. Confirm that the component status aligns with current availability data from authorized distributors. Ensure compatibility with existing board layouts requiring the specified pin configuration and thermal dissipation characteristics.

Video Processing Selection Notes

Select this component when a compact solution for routing multiple video sources to two destinations is required. The integrated drivers eliminate external impedance matching components. Consider the operating temperature range and power supply requirements during system design to ensure stable performance under varying environmental conditions.

Video Processing Part Context

This part belongs to the NJM2279 series of video switches manufactured by Nisshinbo Micro Devices. It is distinct from other series members like the NJM2277, which may offer different channel counts or packaging options. The M suffix specifically denotes the DMP-14 surface mount package variant within this product family.

Video Processing Replacement Considerations

Check for direct substitutes such as the NJM2277 if pin compatibility and feature sets align. Verify that any replacement maintains the same 3x2 channel architecture and 75Ω driver specifications to ensure seamless integration without circuit redesign.
