SN74ACT564PWR

Flip Flops Overview

The SN74ACT564PWR is an octal D-type edge-triggered flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 10.5 ns. The device provides high-level output current of -24 mA and low-level output current of 24 mA. It supports TTL input types and is housed in a TSSOP-20 package for surface-mount installation. The component functions as an inverting logic element suitable for digital data storage applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops
• Three-state outputs enabling direct bus-driven connections without external buffers
• ACT logic series compatibility ensuring CMOS inputs with TTL-compatible levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• High-speed buffering between microprocessors and peripheral devices
• Digital signal processing data registers

Flip Flops Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-20 surface-mount package variant rather than through-hole options. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability fluctuates based on production cycles. Ensure the ordering part number matches the required package style for your PCB layout constraints.

Flip Flops Selection Notes

Select this component when an octal register with three-state capability is required for bus-oriented systems. The ACT series offers faster switching speeds compared to standard 74LS equivalents while maintaining pinout compatibility. Consider the TSSOP-20 package dimensions against available board space and thermal requirements for surface-mount assembly processes.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74ACT family of advanced CMOS logic devices. It serves as a functional equivalent to other octal D-type flip-flops in the industry but utilizes ACT technology for improved performance characteristics. The part integrates eight individual flip-flops into a single integrated circuit for compact digital design implementations.
