74VHCT74AMTC

Overview

The Fairchild Semiconductor 74VHCT74AMTC is a dual D-type flip-flop featuring independent preset and clear inputs. It operates within a voltage range of 2.0V to 5.5V and utilizes a 14-TSSOP surface-mount package. The device supports positive-edge triggering and includes high-impedance states for both preset and clear functions.

Feature Summary

• Dual D-type flip-flop architecture with independent control inputs
• High-impedance preset and clear states for flexible logic management
• Positive-edge clock triggering mechanism

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor operations have transitioned to ON Semiconductor. Confirm that the component matches the original Fairchild specifications and package dimensions. Ensure compatibility with existing design files before finalizing procurement decisions.

Selection Notes

Select this component when a dual D-type flip-flop with active-low preset and clear is required in a TSSOP package. It is suitable for low-voltage digital systems requiring positive-edge triggering. Verify that the VHC technology speed and power characteristics align with the system requirements.

Part Context

This component belongs to the VHCT logic family, which provides CMOS performance with TTL-compatible input levels. The 74VHCT74 variant specifically offers dual flip-flops in a compact surface-mount package, designed for space-constrained digital logic applications requiring reliable data storage capabilities.

Replacement Considerations

The MM74HC74A is an alternative dual D-type flip-flop from the same manufacturer but belongs to the HC series rather than VHCT. Verify voltage level compatibility and pinout alignment before substitution.
