Key Features
- 8-bit serial input and 8-bit serial or parallel output: Allows for flexible data transfer and output configurations.
- Storage register with 3-state outputs: Outputs can be set to high-impedance OFF-state when the output enable input (OE) is HIGH.
- Separate clocks for shift and storage registers: Enables data to be shifted on the LOW-to-HIGH transitions of the SHCP input and transferred to the storage register on the LOW-to-HIGH transition of the STCP input.
- Asynchronous reset MR input: A LOW on MR resets the shift register.
- Serial-to-parallel data conversion: Converts serial input data to parallel output.
- Remote control holding register: Useful for applications requiring data to be held in a register.
- ESD protection: Compliant with ANSI/ESDA/JEDEC JS-001 and JS-002 standards, exceeding 2000 V and 1000 V respectively.
- Automotive qualification: Qualified to AEC-Q100 (Grade 1) standard, suitable for automotive applications.
