74AHCT374D,112

Overview

The 74AHCT374D,112 is an octal D-type flip-flop with positive edge triggering and 3-state outputs, manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features a maximum propagation delay of 10.4 ns at 5 V with a 50 pF load. It supports output drive currents of 8 mA for both high and low states. The component functions across a temperature range of -40 °C to +125 °C and utilizes a 20-pin SO package.

Feature Summary

• Positive edge-triggered octal D-type flip-flop architecture
• Three-state outputs for bus-oriented applications
• CMOS HCT logic levels compatible with TTL inputs

Applications

• Parallel data storage in digital systems
• Bus driver circuits requiring tri-state control
• High-speed clocked memory interfaces

Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and marking details. Ensure the requested quantity aligns with standard manufacturer shipping units. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering.

Selection Notes

Select this component when a wide operating temperature range up to 125 °C is required alongside standard 5 V logic compatibility. The HCT series ensures direct interface with TTL devices while maintaining CMOS power efficiency. Consider the 20-pin SO package dimensions for PCB layout constraints compared to TSSOP alternatives.

Part Context

This part belongs to the 74AHCT family, which combines the speed of Advanced High-Speed CMOS with the input compatibility of High-Speed CMOS TTL-compatible inputs. It serves as a core sequential logic element for storing eight bits of data simultaneously in industrial and commercial electronic designs.

Replacement Considerations

The 74AHCT374PW,118 is a confirmed public substitute offering identical logical functionality in a 20-TSSOP package.
