1. General description

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 VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
