Description

The SN74LS165ADR is an electronic component in the category of shifting registers. It is an 8-bit parallel load or serial-in register with complementary outputs available from the last stage. This component allows for asynchronous parallel inputing when the Parallel Load (PL) input is LOW. Additionally, serial shifting occurs on the rising edge of the clock when PL is HIGH. New data enters the register via the Serial Data (DS) input. The SN74LS165ADR also features a 2-input OR clock that can be used to combine two independent clock sources or as an active LOW clock enable.
