74VHC74MTC

Overview

The Fairchild Semiconductor 74VHC74MTC is a dual D-type flip-flop with independent set and reset inputs, fabricated using advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2.0V to 5.5V and features complementary outputs for each flip-flop. The device includes a master reset function and is designed for high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation. It is housed in a 14-TSSOP surface-mount package.

Feature Summary

• Advanced silicon-gate CMOS fabrication for high-speed performance comparable to Bipolar Schottky TTL
• Dual D-type flip-flops with independent set and reset inputs and complementary outputs
• Integrated master reset functionality for system initialization
• Power-down protection on all inputs and outputs to prevent floating states

Applications

• High-speed digital data storage and transfer registers
• Shift register configurations for serial-to-parallel conversion
• State machine logic implementation in control systems
• Frequency division and pulse synchronization circuits

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor's logic division was acquired by ON Semiconductor. Ensure the component matches the specific 74VHC series specifications rather than legacy HC or HCT variants. Confirm the TSSOP-14 package dimensions and pinout compatibility with your PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when dual D-type flip-flops are required in a compact surface-mount form factor. It is suitable for designs needing high-speed switching at voltages between 2V and 5.5V. Consider its pin compatibility with standard 74HC series if upgrading existing designs, while noting the improved speed characteristics of the VHC family.

Part Context

This part belongs to the 74VHC logic family, which represents advanced high-speed CMOS technology. The VHC series is designed to offer performance levels approaching Bipolar Schottky TTL speeds while retaining the low power advantages of CMOS. The 74VHC74 specifically provides dual flip-flop functionality within this high-performance architecture.

Replacement Considerations

The MM74VHC74MTC is a verified substitute manufactured by ON Semiconductor, reflecting the corporate acquisition. Other compatible alternatives include the SN74VHC74 from Texas Instruments and the MC74VHC74 from onsemi, provided they meet the same electrical and mechanical specifications.
