Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- Separate clocks for the shift and storage registers.
- Serial input (D) and two serial outputs (QS1 and QS2) for cascading.
- Data shifted on LOW-to-HIGH transitions of the CP input.
- Data transfer from shift register to storage register when STR input is HIGH.
- Output enable input (OE) controls the output state; LOW on OE causes outputs to assume a high-impedance OFF-state.
- Inputs include clamp diodes for protection.
