MC74VHCT374ADW

Flip Flops Overview

The MC74VHCT374ADW is an octal D-type flip-flop manufactured by Motorola, belonging to the VHCT logic family. It features a 20-SOIC package with a width of 0.295 inches (7.50mm). The device operates on a single-ended input and provides non-inverting outputs. Key electrical specifications include a maximum clock frequency of 130 MHz and a propagation delay of 10.4 ns. Output drive capabilities are rated at 8 mA for both high and low states. The supply voltage range spans from 4.5 V to 5.5 V.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with eight independent data storage elements
• High-speed CMOS technology enabling operation up to 130 MHz clock frequency
• Three-state output capability for bus-oriented memory applications
• Compatible with standard TTL logic levels through VHCT input structure

Flip Flops Applications

• Bus-oriented memory register implementations
• I/O space buffering for portable systems
• Parallel-to-serial data conversion circuits
• Timing delay compensation networks

Flip Flops Procurement Notes

Verify the manufacturer origin carefully, as this part number was originally produced by Motorola before being acquired by onsemi. Ensure the datasheet corresponds to the specific production era or current onsemi documentation if sourcing from modern distributors. Confirm RoHS compliance status and lead-free designation based on the specific batch or revision code provided by the supplier.

Flip Flops Selection Notes

Select this component when high-speed performance is required within a 5V system. The VHCT series offers faster switching speeds compared to standard HCT devices while maintaining TTL compatibility. The three-state output allows for direct connection to microprocessor buses without additional gating logic. Consider the SOIC-20 package constraints for PCB layout and thermal management requirements.

Flip Flops Part Context

This component is part of the VHCT logic family, which bridges the speed gap between HC and HCT technologies. It serves as an octal flip-flop variant within the broader 74-series logic ecosystem. The device is designed for high-density digital systems requiring fast data latching and bus isolation capabilities in compact surface-mount packages.

Flip Flops Replacement Considerations

MC74VHCT374ADTRG: Same logical function and pinout but packaged in TSSOP-20 instead of SOIC-20. Verify footprint compatibility before substitution. Other VHCT374 variants may differ in packaging or temperature range.
