SN74ACT564N

Flip Flops Overview

The SN74ACT564N is an octal D-type edge-triggered flip-flop from the Texas Instruments 74ACT logic family, housed in a 20-pin PDIP package. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 10.5 ns with drive capabilities of 24 mA for both high and low output states. Designed for through-hole mounting, it supports input levels compatible with TTL standards and functions reliably across an industrial temperature range of -40°C to +85°C.

• Bus interface modules utilizing tri-state control for shared line communication
• Timing synchronization stages in digital logic architectures

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel versus tube packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant matches the required operating temperature range and pinout compatibility for your printed circuit board design before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal register with tri-state outputs is required for high-speed digital designs. The ACT series offers superior speed compared to standard AC devices while maintaining CMOS power efficiency. Verify that the system voltage remains strictly between 4.5 V and 5.5 V to ensure proper logic level translation and avoid exceeding maximum ratings during operation.

Flip Flops Part Context

This part belongs to the Texas Instruments 74ACT logic family, which bridges the performance gap between older TTL technologies and modern CMOS solutions. The SN74ACT564 specifically addresses the need for wide-word data storage in high-frequency applications. Its PDIP-20 form factor facilitates prototyping and legacy system integration where surface-mount alternatives are not feasible.

Flip Flops Replacement Considerations

SN74ACT564DWR (SOIC package), SN74ACT564PW (TSSOP package). Verify pinout compatibility and thermal characteristics when transitioning between package types.
