MC74ACT374NG

Flip Flops Overview

The MC74ACT374NG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features eight edge-triggered flip-flops with individual D-type inputs and three-state true outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes silicon gate CMOS technology for high-speed operation. The component is housed in a 20-pin DIP package suitable for through-hole mounting. It supports a propagation delay of 10 ns at 5 V. The output drivers provide 24 mA sink and source currents. The operating temperature range extends from -40°C to +85°C.

Flip Flops Procurement Notes

Verify the specific suffix NG indicates a 20-pin DIP package when sourcing replacements. Confirm that the ACT series voltage requirements (4.5 V to 5.5 V) match the target system design. Check current availability status as manufacturing statuses may vary. Ensure compatibility with existing PCB footprints if replacing older components. Validate that the three-state output functionality meets the bus architecture requirements.

Flip Flops Selection Notes

Select this component for designs requiring high-speed octal latching with tri-state capability. The ACT series offers faster switching speeds compared to standard AC or HC families while maintaining 5 V compatibility. Consider the 20-pin DIP package for prototyping or legacy board upgrades. Evaluate the 24 mA drive strength against load requirements. Ensure the positive-edge trigger aligns with the system clock polarity.

Flip Flops Part Context

This part belongs to the 74AC/74ACT family of high-speed CMOS logic devices. The MC74ACT374 variant specifically targets 5 V systems with improved speed over previous generations. It serves as a fundamental building block for sequential logic circuits. The octal structure allows efficient handling of wide data buses. It is widely used in digital systems requiring parallel-to-serial conversion or temporary data holding.
