MS2244

Overview

The MS2244 is an integrated video switch designed to select one output from three input video or audio signals. It features a built-in 75Ω driver circuit capable of directly driving television monitors. The device operates within a supply voltage range of 5V to 12V. It provides a bandwidth of 10MHz and achieves an anti-crosstalk performance of 70dB at 4.43MHz.

Feature Summary

Integrates a 75Ω driver circuit for direct monitor connection
Selects one signal from three available inputs
Operates with wide supply voltage flexibility

Applications

Video signal routing in surveillance systems
Audio/Video switching in consumer electronics
Direct drive applications for television monitors

Procurement Notes

Verify the manufacturer origin carefully, as the MS2244 designation appears associated with Ruimeng Technology in technical documentation, while Microsemi is listed in some distributor catalogs. Confirm the specific datasheet source and part marking to ensure compatibility with your system requirements before procurement.

Selection Notes

Choose this component when a compact solution for tri-state video or audio switching is required. The integrated 75Ω impedance matching simplifies board layout by eliminating external termination components. Ensure the operating environment supports the specified 5V-12V supply range and that the 10MHz bandwidth meets the signal frequency needs.

Part Context

Microsemi Corporation, now part of Microchip Technology Inc., specializes in semiconductor solutions for aerospace, defense, and communications. While the MS2244 is linked to Microsemi in certain databases, technical specifications align with Ruimeng's product line, indicating potential cross-referencing or rebranding in distribution channels.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical characteristics against alternative video switches if sourcing from different manufacturers.
