54ACT374WG-MLS

Overview

The 54ACT374WG-MLS is an octal D-type flip-flop manufactured by National Semiconductor, now part of Texas Instruments. It features eight D-type latches with three-state outputs in a single package. The device operates on a single 5V supply and utilizes advanced CMOS technology for high speed and low power consumption. It is designed to provide full parallel access for loading and includes buffered common clock and output enable inputs. The component is available in a 20-lead Small Outline (SOIC) package, suitable for surface mount applications requiring robust bus-driving capabilities.

• Octal D-type flip-flops with three-state outputs
• High-speed operation with low power consumption
• Buffered common Clock and Output Enable inputs
• Latchup immune design

Applications

• Bus-driven memory registers
• Clock distribution systems
• Parallel data acquisition
• I/O buffering

Procurement Notes

Verify the manufacturer source carefully as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix 'WG-MLS' matches the required lead-free and military-grade specifications if applicable. Confirm the package type is indeed the 20-CSOIC variant. Cross-reference the datasheet revision to ensure compatibility with current design requirements. Check for any obsolescence notices from the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when an octal D-type flip-flop with tri-state outputs is required for bus-oriented architectures. It is suitable for applications demanding high speed and low power dissipation under a single 5V supply. Consider the 20-lead SOIC package for surface-mount assembly needs. Verify that the buffered common clock and output enable features align with the system timing constraints. Ensure the latchup immunity meets the environmental reliability standards of the target application.

Part Context

This component belongs to the 54ACT series of logic integrated circuits, which are known for their high-speed performance and compatibility with standard TTL levels. The 54ACT374 specifically provides eight D-type latches, making it a versatile building block for digital systems. As part of the broader family, it shares design principles with other ACT devices, emphasizing low power and fast switching speeds while maintaining robust output drive capabilities for bus applications.

Replacement Considerations

The UT54ACS374 and UT54ACTS374 are functionally similar octal D-type flip-flops with three-state outputs. These alternatives may offer different package options or process variations such as QML certification. Verify pinout compatibility and electrical characteristics before substitution. The 54F374 is another related part but differs in speed and power characteristics. Always consult the specific datasheets to ensure interchangeability.
