Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package variant when sourcing. Confirm that the ACT series designation aligns with required switching speeds and drive capabilities for the target application. Ensure compatibility with 4.5V to 5.5V operating voltages. Check for any lead-free or RoHS compliance markings if environmental regulations apply to the manufacturing process.

Flip Flops Selection Notes

Select this component when an octal storage element with bus-compatible outputs is required. The ACT series offers a balance of speed and power suitable for general-purpose logic applications. Consider the SOIC-20 package for surface-mount assembly constraints. Verify that the 11.5 ns propagation delay meets system timing requirements. Ensure input levels are compatible with TTL standards if interfacing with legacy logic devices.

Flip Flops Part Context

This part is part of the SN74ACT534 family of octal D-type flip-flops. It shares functional similarities with other members like SN74ACT534N but differs in packaging. The DW suffix specifically denotes the small-outline integrated circuit package. It serves as a fundamental building block for sequential logic design within the broader Texas Instruments logic IC portfolio.

Flip Flops FAQ

What is the polarity of the SN74ACT534DW outputs?

The outputs are inverting relative to the D-input state upon clock activation.

Does the SN74ACT534DW require external pull-up resistors for its three-state outputs?

No external pull-up resistors are required for normal operation; the internal structure handles the high state.
