74AHCT374D,118

Flip Flops Overview

The 74AHCT374D,118 is an octal D-type flip-flop with positive edge-triggering and 3-state outputs, manufactured by Nexperia. It belongs to the AHCT logic series, designed for high-speed digital applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a propagation delay of 10.4 ns at 5 V with a 50 pF load. The component provides 8 mA output drive capability in both high and low states. It is housed in a 20-TSSOP surface-mount package and supports operation temperatures from -40 °C to +125 °C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive edge triggering for synchronized data capture
• Three-state outputs enabling efficient bus-oriented system designs and signal isolation
• AHCT logic compatibility allowing direct interface with TTL-level inputs

Flip Flops Applications

• Bus-oriented memory register implementations
• High-speed data acquisition systems requiring precise timing control
• Digital signal processing interfaces utilizing parallel data transfer

Flip Flops Procurement Notes

Verify the specific ordering code suffix to confirm the TSSOP-20 package configuration and reel packaging specifications. Ensure that the design environment strictly adheres to the 4.5 V to 5.5 V supply voltage limits to maintain signal integrity. Confirm thermal management strategies are adequate for the specified operating temperature range during continuous operation.

Flip Flops Selection Notes

Select this component when a wide input voltage tolerance compatible with TTL levels is required alongside high-speed performance. The 3-state output feature makes it suitable for multiplexed bus architectures where multiple devices share data lines. Consider the TSSOP package dimensions for PCB layout constraints compared to alternative SOIC packages.

Flip Flops Part Context

This part is part of the Nexperia 74AHCT374 family of octal flip-flops. It shares functional similarities with other members like the 74AHC374 but differs in input threshold characteristics to support TTL interfacing. The 'D' suffix indicates the SOIC-style footprint variant, while 'PW' denotes TSSOP, though datasheets often group them under similar electrical profiles.

Flip Flops Replacement Considerations

The 74AHCT374PW,118 serves as a pin-compatible alternative offering identical electrical characteristics in a TSSOP-20 package. Verify that any substitute maintains the same 3-state output functionality and propagation delay specifications to ensure circuit compatibility.
