74ABT821D,602

Flip Flops Overview

The NXP USA Inc. 74ABT821D,602 is a high-speed BiCMOS octal D-type flip-flop with clocked outputs, belonging to the 74ABT logic series. It operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs. The device is housed in a 20-pin SSOP package and supports an operating temperature range from -40°C to +85°C. Designed for bus-oriented applications, it provides low input capacitance and fast propagation delays suitable for high-performance data storage systems.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with clocked outputs
• Three-state output capability for bus driving
• High-speed BiCMOS technology for low power consumption
• Wide operating voltage range supporting standard logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching in high-speed data buses
• I/O interface modules requiring data storage
• Clock distribution networks with output control

Flip Flops Procurement Notes

Verify the specific suffix '602' against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing board layouts regarding the SSOP20 footprint. Check for end-of-life status or alternative recommendations directly from NXP channels before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when an octal storage element with controlled output enable is required. The ABT series offers superior speed compared to standard ALS logic while maintaining lower power than older ABT variants. Consider the SSOP20 package constraints and ensure the design accommodates the specified voltage and thermal requirements.

Flip Flops Part Context

This part belongs to the 74ABT family, known for combining the speed of Schottky TTL with CMOS low power. The 74ABT821 variant specifically addresses applications needing multiple synchronized data storage points with individual output control, differing from simpler latch or buffer configurations.

Flip Flops Replacement Considerations

Consult NXP's official replacement guide for direct equivalents. Generic 74ABT821 parts may differ in packaging or electrical tolerances. Verify pinout compatibility and electrical characteristics before substituting with other manufacturers' offerings.
