MC74ACT374DWG

Flip Flops Overview

The MC74ACT374DWG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features eight non-inverting D-type flip-flops with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 160 MHz. Key electrical parameters include a propagation delay of 10 ns at 5 V with 50 pF load, and output drive capabilities of 24 mA for both high and low states. It functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs allow direct connection to bus-oriented systems without additional interface hardware.
• TTL-compatible inputs facilitate seamless integration with standard TTL logic families.
• High-speed performance enabled by ACT technology supporting clock frequencies up to 160 MHz.

Flip Flops Applications

• Register files in digital data processing systems
• Shift registers for serial-to-parallel data conversion
• Bus-oriented memory architectures
• Timing control circuits requiring precise edge-triggered operations

Flip Flops Procurement Notes

Verify that the ordering suffix 'G' confirms RoHS compliance and halogen-free status as per onsemi standards. Confirm the package variant matches the SOIC-20 specification required for your PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check for any specific moisture sensitivity level (MSL) requirements during storage and handling procedures before assembly.

Flip Flops Selection Notes

Select this component when an octal register with three-state output capability is required in a 20-pin surface-mount package. It is suitable for designs needing TTL-compatible input thresholds combined with CMOS output drive strength. Consider the 10 ns propagation delay and 160 MHz clock limit against system timing constraints. Compare against the MC74AC374 if lower voltage operation or wider supply ranges are necessary instead of strict 5V logic levels.

Flip Flops Part Context

This part belongs to the MC74ACT374 family of octal D-type flip-flops. It shares functional similarities with other members like the MC74ACT374DWR2G but differs in packaging format. The DWG suffix specifically denotes the tube-packaged SOIC-20 version, distinguishing it from reel-based variants. It serves as a core building block for sequential logic circuits in industrial and commercial applications.

Flip Flops Replacement Considerations

MC74ACT374DWR2G offers identical logical functionality in a tape-and-reel package for automated assembly. SN74ACT374DWR from Texas Instruments provides a pin-compatible alternative with similar electrical characteristics. CD74ACT374M96 represents another viable substitute from Texas Instruments for design redundancy or supply chain diversification.
