SN74AHCT74N

Flip Flops Overview

The SN74AHCT74N is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74AHCT series. It features CMOS outputs and TTL-compatible inputs, housed in a 14-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8.8 ns, with high-level output current of -8 mA and low-level output current of 8 mA. It supports an operating temperature range from -40°C to +85°C.

Flip Flops Procurement Notes

Verify the specific suffix 'N' corresponds to the 14-pin PDIP through-hole package variant. Confirm that the requested quantity aligns with tube packaging standards typical for this form factor. Ensure the application environment remains within the specified -40°C to +85°C operational temperature limits. Check for any recent product lifecycle notifications regarding obsolescence or last-time buys associated with this specific package style.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with TTL-compatible inputs is required in a through-hole package. The AHCT series ensures compatibility with legacy TTL systems while offering CMOS performance characteristics. Consider the 14-pin PDIP footprint for prototyping or applications requiring manual assembly. Evaluate the 8.8 ns propagation delay against system timing requirements to ensure adequate signal integrity.

Flip Flops Part Context

This part belongs to the SN74AHCT family, which bridges TTL and CMOS technologies. It provides two independent D-type flip-flops per package. The 'N' suffix specifically denotes the plastic dual-in-line package (PDIP) suitable for through-hole mounting. This series is designed for general-purpose digital logic applications requiring reliable state storage and transfer.

Flip Flops Replacement Considerations

Direct pin-to-pin replacements within the same series include SN74AHCT74DR (SOIC-14) and SN74AHCT74PW (TSSOP-14), though these require surface-mount footprints. For identical through-hole packaging, verify availability of SN74AHCT74N equivalents from other manufacturers ensuring matching electrical specifications and pinout compatibility.
