MC74ACT377DWG

Flip Flops Overview

The MC74ACT377DWG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. 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 2V to 6V and supports a maximum clock frequency of 140 MHz. Key electrical parameters include a propagation delay of 10ns at 5V with 50pF load, output drive currents of ±24mA, and a static current of 8µA. It is housed in a 20-SOIC package (0.295" width) and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight independent edge-triggered D-type flip-flops for parallel data storage
• Features a common buffered clock input to synchronize all flip-flops simultaneously
• Provides non-inverting outputs with high current drive capability

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Register file storage elements in digital systems

Flip Flops Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability should focus on remaining stock from authorized distributors or third-party suppliers. Ensure that any sourced units are genuine and match the original specifications, as obsolete parts may vary in condition. Cross-reference with equivalent active components if long-term supply stability is required.

Flip Flops Selection Notes

Select this part only if legacy compatibility with the 74ACT series is mandatory. Note that it lacks the clock enable feature found in the similar MC74ACT377DWR2G variant. Verify that the 20-SOIC package fits the design constraints and that the 2V-6V operating range aligns with the system power architecture. Consider the 140 MHz speed limit for timing analysis.

Flip Flops Part Context

The MC74ACT377DWG is part of onsemi's standard 74AC/74ACT logic family, designed for general-purpose digital logic applications. It serves as a foundational building block for sequential logic circuits. The 'DW' suffix indicates the specific 20-SOIC surface-mount package configuration used in this product code.

Flip Flops Replacement Considerations

The MC74ACT377DWR2G is a parameter-equivalent alternative available from onsemi. While functionally similar, verify if the presence of a clock enable pin in the replacement matches the design requirements, as the DWG variant does not include this feature.
