MC74VHC374M

Flip Flops Overview

The MC74VHC374M is an octal D-type flip-flop featuring three-state outputs, manufactured by onsemi. It operates within a supply voltage range of 2.0V to 5.5V and contains eight independent D-type flip-flops with positive-edge triggering. The device utilizes CMOS input technology and provides non-inverting outputs in a 20-pin SOIC package. Key electrical parameters include a maximum propagation delay of 10.1ns at 5V with 50pF load capacitance, a clock frequency of 120MHz, and output drive currents of 8mA for both high and low states. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive-edge clock triggering
• Three-state outputs allowing direct bus line driving and system expansion
• CMOS input structure ensuring high noise immunity and low power dissipation
• Pin and function compatibility with standard 74HC374 logic families

Flip Flops Applications

• High-speed data storage and buffering in digital systems
• Parallel-to-serial conversion circuits
• Register files and memory interface modules
• Bus driver applications requiring three-state control

Flip Flops Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-20 package variant when sourcing. Confirm RoHS compliance status as legacy documentation may vary. Ensure the supplier provides official datasheets matching the MC74VHC374 designation to avoid confusion with similar VHCT or VHC series parts. Check manufacturing availability as this component may be subject to lifecycle changes.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for 2V to 5.5V systems. It serves as a direct replacement for 74HC374 equivalents while offering improved speed characteristics. Consider the 10.1ns propagation delay for timing-critical designs. Verify that the 8mA output current meets the load requirements of the connected circuitry before finalizing the design.
