MC74ACT377DWR2G

Flip Flops Overview

The MC74ACT377DWR2G is an octal D-type flip-flop with clock enable, manufactured by onsemi using silicon gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features single-ended inputs and outputs. The device provides non-inverting logic with a typical propagation delay of 10 ns. It supports high drive currents of 24 mA for both sourcing and sinking. Packaged in a 20-SOIC surface-mount format, it functions reliably across an industrial temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering and dedicated clock enable functionality.
• Utilizes low-power silicon gate CMOS technology compatible with standard 5V CMOS logic families.
• Delivers strong output drive capability with symmetrical high and low-level current specifications.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage applications in digital systems
• Buffering and latching operations in microprocessor interfaces

Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package type and environmental compliance standards. Confirm that the moisture sensitivity level requirements align with your assembly process timeline. Ensure the operating voltage range of 4.5 V to 5.5 V is compatible with your system power rails before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal register with clock enable is required for 5V logic systems. Consider the 10 ns propagation delay for timing constraints. Compare against the MC74AC377 series if a wider voltage range or different speed characteristics are needed. Verify pinout compatibility if replacing existing designs.

Flip Flops Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It serves as a memory element within digital signal processing chains. The SOIC-20 package allows for efficient PCB layout in space-constrained applications. It complements other 74ACT buffers and drivers in complete logic subsystems.

Flip Flops Replacement Considerations

MC74AC377DWR2G offers similar functionality with extended voltage range. MC74ACT374DWR2G provides tri-state outputs instead of clock enable. Verify pin compatibility and electrical parameters before substitution.

Flip Flops FAQ

What is the function of the clock enable input?

The clock enable input controls whether the flip-flops respond to the clock edge, allowing data to be held or updated.

Is the output inverting or non-inverting?

The MC74ACT377DWR2G features non-inverting outputs, meaning the Q output follows the D input state upon clock activation.
