Key Features
- 8-bit parallel-load or serial-in shift register with complementary serial outputs (Q7 and Q7).
- Parallel data from inputs D0 to D7 can be loaded asynchronously when the parallel-load input (PL) is LOW.
- Data enters the register serially at the input DS when PL is HIGH, shifting one place to the right with each positive-going clock transition.
- Clock input with a gate-OR structure allowing one input to be used as an active LOW clock enable input (CE).
- Operating voltage range from 1.0 V to 5.5 V.
- Operating temperature range from -40 °C to +85 °C.
