74HCT166D: 8-bit parallel-in/serial-out shift register
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 CP input. Inputs include clamp diodes which
enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
