SN74AC564NSR

Flip Flops Overview

The SN74AC564NSR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent circuits with three-state outputs and inverting polarity. The device operates within a supply voltage range of 2 V to 6 V, supporting high drive currents of 24 mA for both high and low states. It exhibits a propagation delay of 14 ns and functions reliably across an industrial temperature range from -40 °C to +85 °C. The component is housed in a TSSOP-20 surface-mount package.

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
• Inverting polarity output characteristic for signal inversion applications

Flip Flops Applications

• Parallel-to-serial data conversion systems
• High-speed buffering and register stages in digital logic circuits
• Data acquisition interfaces requiring tri-state isolation

Flip Flops Procurement Notes

Verify the specific suffix 'NSR' corresponds to the TSSOP-20 package and tape-and-reel orientation. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating environment remains within the specified -40 °C to +85 °C range to maintain performance integrity. Cross-reference pinout diagrams with target PCB layout requirements prior to implementation.

Flip Flops Selection Notes

Select this component when an octal register with tri-state capability and inverting logic is required. The AC series offers faster switching speeds compared to standard 74LS counterparts while maintaining CMOS power efficiency. Verify that the 2 V to 6 V supply range aligns with system voltage rails. Consider the TSSOP-20 footprint constraints during mechanical design integration.

Flip Flops Part Context

This part belongs to the SN74AC564 family of octal D-type flip-flops. It shares functional similarities with non-inverting variants like the SN74AC574 but provides inverted outputs. The NSR suffix indicates a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.
