General description
The 74HC166; 74HCT166 is an 8-bit serial or parallel-in/serial-out shift register.
The device 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 ...
