Flip Flops Procurement Notes

Verify the specific package variant against design requirements, as the SN74LS374 series includes SOIC, SSOP, and PDIP options. Confirm that the selected component matches the required operating temperature range and voltage specifications. Ensure compatibility with existing TTL input levels and check for any specific RoHS compliance documentation if required by manufacturing standards.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for bus interfacing. Consider the LS logic family characteristics regarding speed and power consumption relative to other variants. Verify that the 20-SOIC package fits the available PCB space and thermal constraints. Evaluate the 28 ns propagation delay against system timing requirements to ensure signal integrity.

Flip Flops Part Context

This part is a surface-mount version of the SN74LS374 octal D-type flip-flop. It is part of the broader SN74LS series, which provides standard logic functions using Low-power Schottky technology. The device serves as a fundamental building block for sequential logic circuits requiring data storage and synchronization in digital systems.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes within the same manufacturer's portfolio may include other packaging variants such as SN74LS374DW or SN74LS374DBR. Cross-manufacturer equivalents from other vendors producing standard 74LS374 devices are also viable options provided they meet the same electrical and mechanical specifications.
