Key Features
- Dual independent D-type flip-flops: two fully independent 1-bit storage elements with individual clock, clear, and preset controls
- Positive-edge-triggered operation up to 25 MHz: reliable data capture on rising clock edge for standard-speed digital logic applications
- Active-low clear and preset inputs: enable asynchronous forced initialization or set of outputs independent of clock for fast system control
- HC CMOS logic family: wide supply voltage range with low power consumption compatible with 3.3 V and 5 V systems
Applications
The SN74HC74PWR is a fundamental building block used in digital circuit design for state machines, frequency dividers, and edge detection circuits in microcontroller and FPGA peripheral designs. Its dual configuration with independent clear and preset makes it ideal for clock domain crossing registers and debounce circuits in industrial control and consumer electronics. The HC logic family compatibility ensures it works across 2 V to 6 V supply ranges encountered in battery-powered and mixed-voltage embedded systems.

Frequently Asked Questions
What is the maximum operating frequency of the SN74HC74PWR?
The SN74HC74PWR operates up to 25 MHz at nominal supply voltage with a 50 pF load capacitance, making it suitable for standard-speed digital logic applications such as frequency dividers and shift registers.
What do the clear and preset inputs on the SN74HC74PWR do?
The active-low clear and preset inputs allow asynchronous forced reset or set of each flip-flop output, independent of the clock signal. This is useful for power-on initialization and controlled state forcing in digital systems.
What logic family does the SN74HC74PWR belong to?
It belongs to the HC (High-speed CMOS) logic family, which supports supply voltages from 2 V to 6 V and offers low quiescent current suitable for both 3.3 V and 5 V digital systems.
What package does the SN74HC74PWR come in?
The SN74HC74PWR is available in a 14-pin TSSOP (Thin Shrink Small Outline Package), a compact SMD package that enables high-density PCB designs in space-limited applications.
Can the SN74HC74PWR be used as a frequency divider?
Yes, by connecting the Q-bar output back to the D input, each flip-flop in the SN74HC74PWR divides the input clock frequency by 2, making it a standard choice for clock division in digital timing circuits.
