SN74LVC821APW

Flip Flops Overview

The SN74LVC821APW is a single-element, 10-bit D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features positive-edge triggering with non-inverting, tri-state outputs. The device supports a maximum clock frequency of 150 MHz and exhibits a typical propagation delay of 7.3 ns at 3.3 V with a 50 pF load. It provides symmetric output drive currents of 24 mA for both high and low states, ensuring robust signal integrity in high-speed digital applications.

Flip Flops Feature Summary

• Integrates ten independent D-type flip-flops with positive-edge clock triggering into a single package
• Provides tri-state outputs that allow direct bus line driving without additional interface hardware
• Supports high-speed operation with a maximum clock frequency of 150 MHz

Flip Flops Applications

• High-speed parallel data storage and buffering in digital systems
• Interface circuits requiring level shifting between different voltage domains
• Shift register implementations for serial-to-parallel data conversion

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the packaging type, as the base part number may correspond to tube or reel configurations depending on the full order code. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region and production cycle. Ensure the selected variant matches the required tape-and-reel quantity if automated assembly is planned.

Flip Flops Selection Notes

Select this component when a compact solution for storing ten bits of data is required alongside high-speed performance capabilities. The LVC series offers compatibility with standard CMOS logic levels while supporting lower supply voltages than traditional LVCMOS devices. Consider the 24-TSSOP package dimensions for PCB layout constraints and verify that the operating temperature range meets the environmental requirements of the target application.

Flip Flops Part Context

This device belongs to the SN74LVC821A family of octal transparent latches and D-type flip-flops designed for low-voltage CMOS operations. It is part of Texas Instruments' broader portfolio of logic integrated circuits aimed at reducing power consumption while maintaining high-speed performance. The LVC series is widely used in portable electronics and battery-powered devices due to its efficient voltage operation characteristics.
