74ACT11374DW

Overview

The SN74ACT11374DW is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the 74ACT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 11.3 ns, with high-level output current of -24 mA and low-level output current of 24 mA. It is housed in a 24-pin SOIC package and supports surface mount installation. The component functions over an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Edge-triggered operation synchronized by clock signals for precise timing control
• Three-state outputs allowing direct connection to bus structures without external buffers

Applications

• Parallel-to-serial data conversion circuits
• Buffer memory applications in digital systems
• Register banks for temporary data storage

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel specifications. Ensure the procurement documentation matches the required moisture sensitivity level and RoHS compliance status. Confirm that the supplier provides valid traceability records for the Texas Instruments manufacturing lot. Check for any recent product change notices affecting assembly materials or pin configurations before finalizing orders.

Selection Notes

Select this component when an octal register with tri-state capability is required for 5V logic interfaces. The ACT series offers faster switching speeds compared to standard 74LS equivalents while maintaining compatible input levels. Consider the 24-pin SOIC footprint for PCB layout constraints. Evaluate the 11.3 ns propagation delay against system clock requirements to ensure timing margins are sufficient for the intended application speed.

Part Context

This part is part of the Texas Instruments 74ACT family of advanced CMOS logic devices. It serves as a fundamental building block for sequential logic designs requiring multiple storage elements. The device complements other 74ACT components such as buffers and inverters to create complete digital subsystems. Its octal architecture reduces component count compared to using individual single-bit flip-flops.
