1. General description
The 74HC165-Q100; 74HCT165-Q100 are 8-bit serial or parallel-in/serial-out shift registers.
The device features a serial data input (DS), eight parallel data inputs (D0 to D7) and two
complementary serial outputs (Q7 and Q7). When the parallel load input (PL) is LOW the data from
D0 to D7 is loaded into the shift register asynchronously. When PL is HIGH data enters the register
serially at DS. When the clock enable input (CE) is LOW data is shifted on the LOW-to-HIGH
transitions of the CP input. A HIGH on CE will disable the CP input. Inputs are overvoltage tolerant
to 15 V. This enables the device to be used in HIGH-to-LOW level shifting applications.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
