MC1222F

Flip Flops Overview

The MC1222F is a D-type flip-flop belonging to the Motorola MC1200 series of ECL logic devices. It features a single bit storage element with positive edge triggering and complementary output types. The device supports set and reset functions, operating at a supply voltage of approximately 5.2V with a quiescent current of 27 mA. It is housed in a 14-CFlatPack package and is rated for an operating temperature range extending down to -55°C.

Flip Flops Feature Summary

• Positive edge triggered D-type data storage
• Complementary output configuration
• Integrated set and reset control functions

Flip Flops Applications

• High-speed digital data storage circuits
• ECL-based logic systems requiring fast switching
• Digital signal processing interfaces

Flip Flops Procurement Notes

Verify the specific manufacturer source, as original Motorola production may be discontinued. Confirm package integrity for the 14-CFlatPack variant. Check RoHS compliance status if required by modern assembly standards. Ensure compatibility with existing ECL power supplies and termination networks before procurement.

Flip Flops Selection Notes

Select this component when utilizing the MC1200 ECL family for high-speed applications. Verify that the system design accommodates the 27 mA quiescent current draw. Ensure the 14-CFlatPack footprint matches the PCB layout. Confirm that the negative voltage requirements typical of ECL logic are met by the power distribution network.

Flip Flops Part Context

Part of the MC1200 series, which defines a range of ECL logic components designed for speed-critical applications. This series was widely used in telecommunications and computing infrastructure during the era of emitter-coupled logic dominance. The MC1222F specifically addresses the need for reliable single-bit storage within these high-frequency environments.

Flip Flops Replacement Considerations

Direct substitutes include other MC1200 series D-flip-flops such as the MC1222 or MC1223, provided pinouts and electrical characteristics align. Cross-reference with NXP datasheets for updated equivalents if Motorola sources are unavailable.
