MC14027BDR2G

Flip Flops Overview

The MC14027BDR2G is a dual JK-type flip-flop integrated circuit manufactured by onsemi, belonging to the 4000B CMOS logic series. It features two independent positive-edge-triggered JK flip-flops with set and reset capabilities within a single 16-SOIC package. The device operates over a wide supply voltage range of 3V to 18V and supports a maximum clock frequency of 13 MHz. Key electrical parameters include a static current of 4 µA, output drive currents of 8.8mA for both high and low states, and a maximum propagation delay of 100ns at 15V with a 50pF load. It functions reliably across an extended temperature range from -55°C to 125°C.

Flip Flops Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations exist between tape-and-reel, cut tape, and Digi-Reel formats. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Check lead times carefully, as standard delivery periods may extend significantly beyond initial estimates due to manufacturing constraints. Ensure the selected package variant matches your PCB footprint and automated placement equipment specifications.

Flip Flops Selection Notes

Select this component when designing circuits requiring dual independent memory elements or toggle functionality within a compact surface-mount form factor. The wide voltage tolerance makes it suitable for systems transitioning between different logic levels or operating under variable power conditions. Consider the propagation delay characteristics when determining suitability for high-speed synchronous applications relative to system clock frequencies.

Flip Flops Part Context

This part belongs to the MC14027B family, which provides dual JK flip-flops in various packages including SOIC and DIP configurations. The 'DR' designation indicates a specific reel-based packaging format optimized for automated surface-mount assembly processes. It serves as a fundamental building block in complex digital logic designs requiring reliable bistable multivibrator functionality.

Flip Flops Replacement Considerations

Direct substitutes include other manufacturers' dual JK flip-flops such as the CD4027 series. Verify pin compatibility and electrical parameter alignment before substitution. Alternative packages like DIP variants may require adapter solutions if through-hole mounting is necessary instead of surface-mount technology.

Flip Flops FAQ

What type of triggering does the MC14027BDR2G use?

The device utilizes positive-edge triggering for its JK flip-flops, meaning state changes occur on the rising edge of the clock signal.

Does the MC14027BDR2G have asynchronous control inputs?

Yes, each flip-flop includes dedicated Set (Preset) and Reset inputs that allow immediate state initialization independent of the clock signal.
