MC74AC374DTR2G

Flip Flops Overview

The MC74AC374DTR2G is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features eight non-inverting D-type flip-flops with three-state outputs in a single package. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 155 MHz. Key electrical parameters include a propagation delay of 9.5 ns at 5V with 50pF load, static current of 8 µA, and output drive capability of ±24 mA. It is housed in a 20-TSSOP surface-mount package.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type flip-flops for parallel data storage.
• Three-state outputs allow direct connection to bus lines without external drivers.
• Positive-edge triggering ensures data capture occurs on the rising edge of the clock signal.
• High-speed CMOS technology enables operation up to 155 MHz with low power consumption.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register files and buffer memory applications
• Clock domain crossing synchronization stages
• Digital signal processing data path buffering

Flip Flops Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-20 package and tape-and-reel packaging format. Confirm RoHS compliance status as indicated by the 'G' suffix. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during integration.

Flip Flops Selection Notes

Select this component when high-speed data latching is required with low power dissipation. The AC series offers faster performance than HC variants while maintaining compatibility with standard logic levels. Consider the ±24 mA output drive strength for moderate capacitive loads. Verify that the 2V to 6V operating range aligns with the system's available supply voltages.

Flip Flops Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices. It serves as a digital storage element within larger integrated systems. The octal design reduces board space compared to using multiple single-bit flip-flops. It is commonly used in microprocessor-based systems requiring temporary data holding capabilities.

Flip Flops Replacement Considerations

• MC74AC374DWR2G (Same family, SOIC-20 package)
• SN74AC374PWR (Texas Instruments equivalent, TSSOP-20 package)

Flip Flops FAQ

What is the trigger mechanism for the MC74AC374DTR2G?

The device uses positive-edge triggering, meaning the D inputs are sampled and transferred to the outputs on the rising edge of the clock signal.

Does the MC74AC374DTR2G have internal pull-up resistors?

No, the datasheet does not specify internal pull-up resistors. External termination may be required depending on the application circuit design.
