74VHC74MTCX

Overview

The 74VHC74MTCX is a Dual D-Type Flip-Flop with Preset and Clear manufactured by Fairchild Semiconductor. It utilizes advanced high-speed CMOS technology in a 16-TSSOP package. The device operates within a supply voltage range of 2V to 5.5V, featuring low static power consumption of 4 µA maximum. It supports a clock frequency up to 115 MHz and includes positive-edge triggering functionality.

Feature Summary

• Dual D-type flip-flop architecture with independent preset and clear inputs
• Advanced high-speed CMOS fabrication for performance comparable to Bipolar Schottky TTL
• Power-down protection provided on all inputs to prevent floating states

Applications

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

Procurement Notes

Verify the manufacturer designation matches Fairchild Semiconductor or its successor entity ON Semiconductor. Confirm the package marking corresponds to the 16-TSSOP form factor. Ensure the component meets RoHS compliance standards as indicated in official documentation. Cross-reference the full part number including suffixes against distributor catalogs to ensure exact functional equivalence.

Selection Notes

Select this component when dual edge-triggered storage is required in space-constrained designs. The VHC series offers superior speed compared to standard HC logic while maintaining low power dissipation. Verify that the operating voltage range aligns with the system's 2V to 5.5V requirements. Consider the 16-TSSOP footprint for surface-mount assembly compatibility.

Part Context

This component belongs to the 74VHC family of advanced high-speed CMOS logic devices. The VHC series is designed to provide high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation typical of CMOS technology. It serves as a direct pin-compatible replacement for older logic families in modern digital systems.
