HD74HC166 Datasheet (Renesas) - Parallel-load 8-bit Shift Register

HD74HC166, Parallel-load 8-bit Shift Register

This device is an 8-bit shift register with an output from the last stage.

Data may be loaded into the register either in parallel or in serial form.

When the Shift/Load input is low, the data is loaded asynchronously in parallel.

When the Shift/Load input is high, the data is loaded serially on the
