The 74HC165PW/S911118 is an integrated circuit (IC) component commonly used in digital electronics. It belongs to the 74HC series, which are high-speed CMOS (Complementary Metal-Oxide-Semiconductor) devices. The 74HC165PW/S911118 is specifically a shift register with parallel input and serial output.
The key features of the 74HC165PW/S911118 IC component include:
1. Parallel Input: The IC has eight parallel input pins (P0-P7) that allow data to be loaded simultaneously.
2. Serial Output: The IC has a single serial output pin (QH') that provides the shifted-in data serially.
3. Shift Register: It has an internal 8-bit shift register that can be loaded by shifting in data serially. The shift register holds the data until it is parallelly transferred to the output on a parallel load signal.
4. Clock Pulse Input: The IC requires a clock pulse (CLK) input for shifting data through the shift register.
5. Data Input Enable: The IC has an input pin (SH/LD) that enables or disables the parallel input. When the SH/LD pin is low, data at the parallel inputs gets loaded into the shift register. When it is high, the parallel inputs are disabled, allowing the serial data input to shift through the shift register
