74ABT821D,623

Flip Flops Overview

The NXP USA Inc. 74ABT821D,623 is a single-element D-type flip-flop belonging to the ABT logic series. It features a 10-bit configuration with positive edge triggering and true outputs. The component utilizes BICMOS technology and is housed in a 24-SOIC package (0.295 inch / 7.50 mm width). It operates within a supply voltage range of 2.3 V to 3.6 V. Maximum propagation delay is specified at 6.2 ns at 5 V with 50 pF load, though standard operation is defined for the 2.3-3.6 V range.

Flip Flops Feature Summary

• Single-element D-type flip-flop architecture providing 10-bit data storage capability
• Positive edge-triggered operation ensuring synchronized data capture
• True output configuration delivering non-inverted signal states
• BICMOS technology implementation for high-speed digital processing

Flip Flops Applications

• High-speed parallel data buffering in digital systems
• Synchronous state retention in microprocessor interfaces
• Data latching in communication protocol controllers
• Register file construction in embedded logic circuits

Flip Flops Procurement Notes

Verify the specific suffix '623' corresponds to the Tape & Reel packaging format when sourcing. Confirm the manufacturer designation as NXP USA Inc. matches project requirements. Ensure compatibility with the 24-SOIC footprint dimensions during PCB layout finalization. Cross-reference RoHS compliance status if environmental regulations apply to the assembly process.

Flip Flops Selection Notes

Select this component for applications requiring 10-bit synchronous storage with minimal propagation delay. The ABT series offers improved speed compared to standard ALS logic. Verify that the operating voltage aligns with the 2.3 V to 3.6 V specification. Consider the SOIC package size constraints relative to available board space and thermal management needs.

Flip Flops Part Context

This device is part of the broader 74ABT family of high-speed CMOS logic devices. It shares functional similarities with other 10-bit registers but distinguishes itself through specific packaging and trailing order codes. The ABT series is designed for demanding digital applications requiring fast switching speeds and low power consumption.

Flip Flops Replacement Considerations

The 74ABT821DB,112 serves as a variant within the same logical family, differing primarily in SSOP24 packaging rather than core functionality. Verify pinout compatibility before substitution. Other 10-bit D-type flip-flops from the ABT series may require level shifting or voltage adjustment.
