74LV165 8-bit parallel-in/serial-out shift register Rev. 8 21 September 2021 Product data sheet 1. General description The 74LV165 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 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 include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess V . CC 2.
