概述

Description

The 74LV165D is an 8-bit serial-in, parallel-out shift register, part of the LV (Low Voltage) family of integrated circuits. It operates from a supply voltage of 2.0V to 5.5V, making it suitable for low-power applications. The device allows for data to be shifted in serially through a single input pin and then output in parallel across eight output pins.
Key features include a clock input for synchronizing data shifts, a serial data input, and a parallel output that can be used to drive LEDs or other devices. It also features a reset function to clear the register contents. The 74LV165D is commonly used in applications such as data storage, digital signal processing, and interfacing with microcontrollers.
Its compact packaging and ease of integration make it a popular choice for both hobbyists and professionals in designing efficient digital systems.

Features

The 74LV165D is an 8-bit serial-in/parallel-out shift register with the following key features:
1. 8-Bit Storage: It can store 8 bits of data.
2. Serial Input: Data can be shifted in serially on the DS (data serial) input.
3. Parallel Output: Outputs are available for all 8 bits, allowing simultaneous access.
4. Shift Control: Controlled by clock (CLK) and latch (STROBE) inputs, facilitating data shifting and storage.
5. Low Voltage Operation: Designed for low voltage operation (2V to 5.5V), making it suitable for modern digital circuits.
6. High-Speed Performance: Capable of high-speed shifting with a maximum clock frequency of up to 100 MHz.
7. Low Power Consumption: Consumes less power than older technologies, enhancing battery life in portable devices.
8. TTL Compatible: Compatible with TTL logic levels, ensuring interoperability with other TTL devices.
This makes the 74LV165D ideal for applications in digital signal processing, data communication, and interfacing with microcontrollers.
