74LVC821ABQ,118

Overview

The 74LVC821ABQ,118 is a single-element D-type flip-flop with 10-bit width manufactured by Nexperia. It operates within a supply voltage range of 1.2 V to 3.6 V and features positive-edge triggering. The device is housed in a 24-VFQFN exposed pad package. It supports low-voltage CMOS technology compatible with TTL families.

Feature Summary

• Single-element D-type flip-flop architecture providing 10-bit data storage capability
• Positive-edge clock triggering mechanism for synchronous data capture
• Low-power high-performance silicon-gate CMOS construction
• Compatible with standard TTL logic families across the operating voltage range

Applications

• General-purpose digital data storage circuits
• Synchronous state machine implementations
• Parallel-to-serial data conversion interfaces
• Memory buffer applications in low-voltage systems

Procurement Notes

Verify the manufacturer designation carefully as sources list both NXP USA Inc. and Nexperia. Confirm the specific suffix ABQ indicates the QFN package variant. Ensure compatibility with the required 1.2 V to 3.6 V supply rails. Check for RoHS compliance documentation if environmental standards are mandatory for the application.

Selection Notes

Select this component when a compact 10-bit parallel register is required in space-constrained designs. The VFQFN package offers a small footprint suitable for dense PCB layouts. Ensure the system design supports the specified voltage range and utilizes positive-edge clocking. Consider thermal dissipation requirements given the exposed pad configuration.
