Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register.
- Separate clock and reset inputs for both shift and storage registers.
- Data is shifted on the LOW-to-HIGH transitions of the SHCP input, and transferred to the storage register on a LOW-to-HIGH transition of the STCP input.
- Inputs can be driven from either 3.3 V or 5 V devices, making it suitable for mixed voltage environments.
- Schmitt-trigger action at all inputs for tolerance of slower input rise and fall times.
- Low power dissipation and fully specified for partial power down applications.
