The MC74LS175DR is a Quad D-Type Flip-Flop with Clear from the 74LS series, manufactured by Freescale Semiconductor (NXP). It contains four independent D-type flip-flops in a single package, each capable of storing one bit of data. The data present at the D input is transferred to the Q output on the positive-going edge of the clock pulse. The common clear input allows all four flip-flops to be reset simultaneously.
Applications
- Data Storage: Storing digital data temporarily for processing or transfer.
- Parallel Data Buffering: Buffering parallel data lines in digital systems.
- Address Latching: Latching address lines in memory systems.
- Control Register: Implementing control registers in microprocessor-based systems.
- Shift Registers: Building shift registers by cascading multiple flip-flops.
Features
- Quad D-Type Flip-Flop: Contains four independent D-type flip-flops in a single package.
- Positive-Edge Triggered: Data is transferred to the output on the positive-going edge of the clock pulse.
