74HC166-Q100; 74HCT166-Q100

8-bit parallel-in/serial out shift register

The 74HC166-Q100; 74HCT166-Q100 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 V_CC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
