74LVC821APW,112

Overview

The 74LVC821APW,112 is an octal D-type flip-flop with 3-state outputs manufactured by NXP. It operates within a supply voltage range of 1.2 V to 3.6 V and utilizes a TSSOP-20 package. The device features independent data inputs and outputs, controlled by a common clock (CLK) and output enable (OE) signals. It supports high-speed operation with low power consumption, typical for the LVC logic family.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent storage elements
• Three-state outputs allowing direct bus connection without external buffers
• Wide operating voltage range supporting both 1.8 V and 3.3 V systems
• Low power consumption characteristics suitable for battery-powered applications

Applications

• Parallel-to-serial data conversion in communication interfaces
• Buffering and register functions in microprocessor-based systems
• Data acquisition systems requiring temporary data storage
• Industrial control panels for I/O signal latching

Procurement Notes

Verify the complete part number including the suffix ',112' which indicates tape and reel packaging. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the supplier provides original manufacturer documentation to guarantee authenticity. Check for any specific handling requirements related to electrostatic discharge during procurement and storage.

Selection Notes

Select this component when an octal register with tri-state capability is required. Compare propagation delay specifications against system timing constraints. Consider the TSSOP-20 package size relative to PCB layout limitations. Evaluate power supply noise immunity if operating near the lower voltage limits of the specified range.

Part Context

This component belongs to the 74LVC series, designed for low-voltage CMOS applications. It complements other logic families like 74LV and 74LVC by offering optimized performance at 1.8 V and 3.3 V. The device is part of NXP's extensive portfolio of standard logic ICs used in consumer electronics and industrial equipment.

Replacement Considerations

Check for pin-compatible alternatives from the same 74LVC family. Verify that substitute parts meet the same electrical characteristics and package dimensions. Ensure availability of equivalent components from authorized distributors to maintain supply chain stability.
