Flip Flops Procurement Notes

Verify the specific suffix 'AN' corresponds to the 20-DIP package variant when sourcing. Confirm RoHS compliance status via official documentation as requirements vary by region. Ensure thermal management aligns with the specified -55°C to +125°C operating range during integration. Cross-reference pinout diagrams with target PCB layout to prevent orientation errors during assembly.

Flip Flops Selection Notes

Select this component when designing systems requiring parallel data retention with bus isolation capabilities. The HCT series compatibility ensures seamless integration with legacy TTL logic levels without additional interface circuitry. Consider the 31 ns propagation delay for timing-critical paths. Evaluate the 20-DIP package constraints against available board space and mounting preferences compared to SMD alternatives.

Flip Flops Part Context

This part belongs to the MC74HCT374A family of octal flip-flops produced by onsemi. It serves as a core building block for sequential logic circuits within broader semiconductor portfolios.
