The 74HC166D is a 8-bit parallel-in/serial out Shift Register features a serial data input DS, eight parallel data inputs D0 to D7 and a serial output Q7. When the parallel enable input PE\\ is low, the data from D0 to D7 is loaded into the shift register on the next low-to-high transition of the clock input CP. When PE\ is high, data enters the register serially at DS with each low-to-high transition of CP. When the clock enable input CE\\ is low data is shifted on the low-to-high transitions of CP. A high on CE\ disables the CP input. Inputs include clamp diodes which enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
