Key Features
- Dual independent D-type flip-flop with active-low preset and clear, enabling direct forced-state control without a clock edge
- HC CMOS family operation from 2 V to 6 V supply with 20 MHz maximum clock frequency and 4 mA output drive strength
- 14-pin SOIC surface-mount package in tape-and-reel format for automated PCB assembly in high-volume digital logic designs
Applications
CD74HC74MTG4 is used in frequency dividers, shift register stages, synchronous state machines, and clock domain crossing circuits where two independent edge-triggered storage elements are needed in a single small-outline package. Its 20 MHz maximum clock frequency and HC-family CMOS noise margins make it a reliable building block for microcontroller peripheral interfaces, sensor data latching circuits, and low-speed digital control logic in industrial and consumer electronics.

Frequently Asked Questions
What is the maximum operating clock frequency of CD74HC74MTG4 and at what load capacitance is this specified?
CD74HC74MTG4 supports a maximum clock frequency of 20 MHz at a load capacitance of 50 pF with a 4.5 V supply. This HC-family speed is well-suited for low-to-medium-speed synchronous logic such as frequency division, debouncing circuits, and data latching in microcontroller peripheral designs.
How do the active-low preset and clear inputs on CD74HC74MTG4 work, and when are they useful in circuit design?
The active-low preset (PRE) and clear (CLR) inputs on each CD74HC74MTG4 flip-flop asynchronously force the Q output to logic high or logic low respectively, independent of the clock. This is useful for initializing state machines, clearing shift register pipelines at power-up, or implementing hardware reset logic without requiring a clock edge to propagate the reset state through the circuit.
When should a designer choose CD74HC74MTG4 over a 74AC74 flip-flop for a 5 V synchronous logic design?
CD74HC74MTG4 is the better choice when power consumption is more important than speed, since the HC family typically draws 10x to 100x less quiescent current than AC-family devices at low frequencies. However, if the design requires clock frequencies above 20 MHz or maximum output drive beyond 4 mA at 5 V, the 74AC74 is more appropriate due to its 90 MHz maximum frequency and 12 mA output drive.
