Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register.
- 3-state outputs to reduce bus contention when connected to a common data bus.
- Separate clocks for shift and storage registers, allowing for flexible data transfer.
- Serial input (D) and two serial outputs (QS1 and QS2) for cascading multiple devices.
- Output enable input (OE) to control the output state, allowing the outputs to assume a high-impedance OFF-state when OE is LOW.
- High-speed CMOS logic family (74HC), ensuring low power consumption and high noise immunity.
Applications
- Data storage and transfer in digital systems, such as in microcontrollers, microprocessors, and other digital circuits.
- Serial-to-parallel data conversion in communication systems and data transmission protocols.
- Cascading applications where multiple shift registers need to be connected in series.
- Bus-oriented systems where the 3-state outputs are beneficial for reducing bus contention.
