The HD74HC165FP(EL-E) is an 8-bit parallel-load shift register, manufactured by Renesas Electronics, belonging to the High-Speed CMOS (HC) logic family. This device loads data in parallel and then shifts it out serially, making it ideal for converting parallel data to serial data.

Applications:

• Parallel-to-serial data conversion: Used in applications where parallel data needs to be converted into serial data for transmission or processing.
• Keyboard and keypad scanning: Employed in scanning keyboards and keypads to detect key presses.
• Remote data acquisition: Utilized in remote data acquisition systems to transmit data serially over long distances.
• Microcontroller interfacing: Integrated into microcontroller systems for serial data communication.

Features:

• 8-bit parallel-load: Loads data in parallel onto eight input lines.
• Serial output: Shifts data out serially on a single output line.
• Synchronous loading: Data is loaded on the rising edge of the load enable input.
• Clock enable input: Controls the shifting operation.
• Wide operating voltage range: Operates from 2V to 6V, providing compatibility with various logic levels.

Benefits:

• Reduced wiring complexity: Converts parallel data to serial data, reducing the number of wires required for transmission.
• Simple interface: Easily interfaces with microcontrollers and other digital devices.

Additional Details:

The HD74HC165FP(EL-E) typically operates with a supply voltage of 5V. The maximum clock frequency is around 25 MHz. The device features TTL-compatible inputs and outputs.
