ON Semiconductor 74HC74 Dual D-Type Flip-Flop
The 74HC74 is a high-speed Si-gate CMOS device from ON Semiconductor that is designed to operate at the same level as the original 74-series logic ICs. This dual D-type flip-flop is a versatile component used in a wide array of digital applications, from frequency division to state storage and toggle functions.
Each flip-flop has independent direct clear and direct set inputs, as well as a clock input and an output and inverted output. The device transitions on the positive-going edge of the clock pulse, and the set and reset inputs are asynchronous, providing immediate control over the output independent of the clock.
Key Features:
- Logic Type: Dual D-Type Positive Edge Triggered Flip-Flop
- Operating Voltage: 2V to 6V
- High Noise Immunity: NIV = VNIH = VNIL = 28% VCC (Min)
- Power Dissipation: Low power consumption, balanced propagation delays
- Output Drive Capability: 10 LSTTL Loads
- Symmetrical Output Impedance: |IOH| = IOL = 4 mA (Min)
- Pin Configuration: Standard 14-pin DIP or SOIC package
- Temperature Range: -55 to +125 degrees Celsius
The 74HC74 is ideal for edge-triggered applications and provides a reliable solution for data storage, data transfer, and frequency division. Its compatibility with LSTTL outputs, along with the ability to drive 10 LSTTL loads, makes it a suitable choice for interfacing with legacy digital systems as well as newer designs.
ON Semiconductor ensures the highest quality and reliability of their components. The 74HC74 is no exception, offering robust performance for both commercial-grade and industrial applications. Its wide operating temperature range makes it suitable for demanding environments, ensuring that your digital circuits maintain their integrity under varying conditions.
Whether you're designing flip-flops for timing circuits, counters, or toggle circuits, the 74HC74 from ON Semiconductor is an excellent choice that combines performance with durability.
