概要

Description

The 74LV164PW is an 8-bit serial-in, parallel-out shift register designed for low-voltage applications. It operates at a voltage range of 2V to 5.5V, making it suitable for modern digital circuits. The device has two primary modes of operation: serial input, where data is shifted in one bit at a time, and parallel output, where all bits can be accessed simultaneously.
Key features include a low power consumption, a high-speed operation, and the ability to cascade multiple units for expanded bit-width applications. The 74LV164PW utilizes CMOS technology, providing high noise immunity and rapid switching times. It comes in various packages, including DIP and SOIC, facilitating easy integration into both prototyping and commercial products.
This shift register is commonly used in applications such as LED control, data storage, and interfacing with microcontrollers. Its ability to efficiently handle data makes it a staple in digital design and electronics.

Package

The 74LV164PW is packaged in a TSSOP (Thin Shrink Small Outline Package) format.

Pinout

The 74LV164PW is an 8-bit serial-in, parallel-out shift register. It has 16 pins in total. Here’s a brief description of its pin functions:
1. VCC (Pin 1): Power supply (+2V to +5.5V).
2. GND (Pin 8): Ground reference.
3. DS (Pin 2): Serial data input.
4. SH/LD (Pin 3): Shift/Load control input. When high, it shifts data; when low, it loads the data from the parallel inputs.
5. MR (Pin 4): Master Reset input, which clears the shift register when low.
6. Q0 to Q7 (Pins 5-7, 9-11, 13-15): Parallel outputs (Q0 is the first bit shifted out).
7. CLK (Pin 6): Clock input for shifting data.
8. PL (Pin 12): Parallel Load input. When low, the data on the parallel inputs is loaded into the register.
The 74LV164PW operates at low voltage and offers high-speed operation, making it suitable for various digital applications.
