SN74ABT574APWR

Flip Flops Overview

The SN74ABT574APWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It belongs to the ABT logic series and features three-state outputs for bus-oriented applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 6.6 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is housed in a TSSOP-20 surface-mount package.

Flip Flops Feature Summary

• Octal configuration with eight independent D-type flip-flops
• Three-state outputs facilitate direct bus system connections
• Edge-triggered data storage on the positive clock transition
• Non-inverting polarity for standard signal path integration

Flip Flops Applications

• Bus-oriented memory mapping systems
• Register file implementations
• Parallel-to-serial data conversion circuits
• General-purpose digital storage modules

Flip Flops Procurement Notes

Verify that the ordering suffix matches APWR to confirm the TSSOP-20 package type. Ensure the component meets RoHS compliance requirements if specified for the project. Confirm the manufacturer source is Texas Instruments or an authorized distributor to guarantee authenticity. Check datasheet revisions for any updates regarding recommended operating conditions.

Flip Flops Selection Notes

Select this component when an octal register with high drive capability is required. The ABT series offers faster switching speeds compared to standard LS logic. Verify that the 4.5 V to 5.5 V supply range aligns with the system power rails. Consider the TSSOP-20 footprint constraints during PCB layout design.

Flip Flops Part Context

This part is a member of the SN74ABT574A family, which includes variants with different packages such as SSOP and SOIC. The 'PWR' suffix specifically denotes the plastic small-outline TSSOP package with a reel tape format. It serves as a standard solution for 8-bit data latching in 5V logic environments.

Flip Flops FAQ

What is the trigger mechanism for the flip-flops?

The flip-flops are edge-triggered, meaning data is captured at the positive-going transition of the clock signal.

Does the device support bidirectional data flow?

No, the SN74ABT574APWR is unidirectional. For bidirectional bus drivers, consider the SN74ABT541B series instead.
