MC74ACT377MELG

Flip Flops Overview

The MC74ACT377MELG is an octal D-type flip-flop from onsemi's 74ACT series, housed in a 20-lead SOIC package. It features eight edge-triggered D-type flip-flops with individual data inputs and non-inverting outputs, alongside a common buffered clock input. The device operates within a supply voltage range of 4.5V to 5.5V, delivering high-level output currents of -24mA and low-level output currents of 24mA. Key electrical specifications include a maximum propagation delay of 10ns at 5V with 50pF load and a clock frequency capability of 140MHz.

Flip Flops Feature Summary

• Contains eight positive-edge triggered D-type flip-flops with independent data inputs and Q outputs.
• Includes a common buffered Clock (CP) input for synchronized operation across all stages.
• Provides non-inverting single-ended outputs with robust drive capabilities.
• Utilizes silicon gate CMOS technology for standard 5V logic compatibility.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register storage applications requiring high-speed data latching
• Buffering registers in digital signal processing systems
• General-purpose memory elements in microprocessor-based designs

Flip Flops Procurement Notes

Verify the specific suffix MELG corresponds to the tape and reel packaging format when sourcing components. Confirm that the ordering part number matches the exact package dimensions and pinout requirements for your PCB layout. Ensure compliance with RoHS directives as indicated by the manufacturer documentation. Cross-reference the datasheet revision history to confirm parameter consistency for production integration.

Flip Flops Selection Notes

Select this component when designing systems requiring eight parallel bits of storage with a single clock control line. The ACT series offers faster switching speeds compared to standard AC counterparts while maintaining 5V CMOS compatibility. Consider the 20-lead SOIC package constraints for board space limitations. Evaluate the 10ns propagation delay against system timing budgets to ensure signal integrity at the target clock frequencies.

Flip Flops Part Context

This device belongs to the 74ACT family of high-speed CMOS logic devices manufactured by onsemi. It is functionally compatible with other industry-standard octal D-flip-flop architectures but optimized for specific voltage and speed characteristics defined by the ACT series guidelines. The component serves as a fundamental building block for sequential logic circuits in industrial and consumer electronics.
