Overview
The 74HCT165D,652 is an 8-bit parallel-in/serial-out shift register produced by Nexperia USA Inc. This device is part of the 74HCT family, which operates at TTL (Transistor-Transistor Logic) levels. It features a serial data input (DS), eight parallel data inputs (D0 to D7), and two complementary serial outputs (Q7 and Q7'). The shift register can load data asynchronously from the parallel inputs when the parallel load input (PL) is LOW, or serially through the DS input when PL is HIGH. The clock enable input (CE) controls the shifting of data, which occurs on the LOW-to-HIGH transitions of the CP input.
