SN74ACT564PW

Flip Flops Overview

The SN74ACT564PW is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10.5 ns at 5 V with 50 pF load. The device provides high drive capability with output currents of ±24 mA. Designed for through-hole mounting, it utilizes a 20-pin TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit.
• Three-state outputs enable direct connection to bus structures without external buffer circuits.
• ACT logic series compatibility ensures fast switching speeds and low power consumption relative to standard TTL.

Flip Flops Applications

• Parallel-to-serial data conversion in communication interfaces
• Register storage within microprocessor-based systems
• Buffering digital signals on system buses

Flip Flops Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant rather than other packaging options like DIP or SOIC. Confirm that the ordering part number matches the required pinout and thermal characteristics for your PCB layout. Ensure compliance with RoHS directives if environmental regulations apply to your manufacturing process.

Flip Flops Selection Notes

Select this component when an octal register with tri-state control is required for 5V logic systems. Consider the ACT series for improved speed over standard 74LS devices while maintaining TTL input compatibility. Evaluate the TSSOP package size against available board space constraints compared to larger DIP alternatives.
