MC74HCT574AN

Flip Flops Overview

The MC74HCT574AN is an octal D-type flip-flop from onsemi's HCT logic series, housed in a 20-pin DIP package. It features non-inverting outputs and positive edge triggering. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 30 ns, with high-level output current of -6 mA and low-level output current of 6 mA. It supports single-ended inputs and outputs, functioning across a temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit.
• LSTTL-compatible input thresholds ensuring seamless interface with standard logic families.
• Positive edge-triggered operation for precise data capture synchronized with clock signals.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage elements in digital systems
• Buffer memory applications requiring latch functionality

Flip Flops Procurement Notes

Verify the specific suffix 'AN' corresponds to the 20-DIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the procurement channel provides valid traceability for industrial-grade components operating at extended temperatures.

Flip Flops Selection Notes

Select this component when an octal register with LSTTL compatibility is required in a through-hole DIP format. Compare against surface-mount variants like the ADWR2G if PCB space constraints necessitate SMD packaging. Verify that the 30 ns propagation delay meets the timing requirements of the target application speed.

Flip Flops Part Context

This part belongs to the MC74HCT574A family of octal D-type flip-flops. It serves as a legacy through-hole alternative to modern surface-mount packages while maintaining the same logical functionality and electrical characteristics defined by the HCT series specifications.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include MM74HCT574MTC (TSSOP) and MM74HCT574WMX (SOIC). Note that these alternatives differ in package type and may require PCB layout adjustments despite identical logical function.
