SN74AC564DBR

Flip Flops Overview

The SN74AC564DBR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, featuring inverting outputs and a three-state interface. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 20-SOIC package. The device exhibits a propagation delay of 14 ns, with high-level and low-level output currents rated at -24 mA and 24 mA respectively. It functions reliably across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered storage elements
• Inverting logic polarity for direct signal inversion upon clock triggering
• Three-state output capability allowing bus line sharing and isolation

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital data buses
• General-purpose register implementations in logic systems

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 20-SOIC footprint matches the target PCB layout dimensions. Ensure the operating voltage environment remains strictly within the 2 V to 6 V specification to maintain signal integrity and prevent device damage during operation.

Flip Flops Selection Notes

Select this component when an octal storage solution with inverting functionality and three-state outputs is required. The AC series offers a balance of speed and drive strength suitable for general logic applications. Consider the 20-SOIC package constraints and the 14 ns propagation delay against system timing requirements before finalizing the design integration.

Flip Flops Part Context

This part belongs to the SN74AC564 family of octal D-type flip-flops. It shares architectural similarities with non-inverting variants like the SN74AC574 but provides inverted outputs. The device is part of Texas Instruments' broader 74AC logic portfolio, designed for CMOS compatibility and robust performance in standard digital logic environments.
