The 54ACT175DMQB is a high-performance, radiation-hardened Quad D Flip-Flop with Clear from Fairchild Semiconductor (now ON Semiconductor). This device is designed for use in military and aerospace applications requiring reliable performance in harsh environments.

Applications:

• Memory Storage: Used as a fundamental building block in memory systems for storing data bits.
• Shift Registers: Employed in shift registers for serial-to-parallel or parallel-to-serial data conversion.
• Data Latches: Utilized as data latches to hold data temporarily.
• Control Registers: Implemented in control registers for storing and controlling system parameters.
• Digital Signal Processing (DSP): Integrated into DSP systems for data storage and manipulation.

Features:

• Quad D Flip-Flops: Contains four independent D-type flip-flops in a single package.
• Positive-Edge Triggered: Data is clocked into the flip-flop on the positive-going edge of the clock signal.
• Asynchronous Clear Input: Provides an immediate clear function, overriding the clock and data inputs.
• High-Speed Operation: Offers fast propagation delays for high-performance applications.
• Radiation Hardened: Designed to withstand radiation exposure in space and other harsh environments.
