概述

Description

The SN74HC164PW is an 8-bit serial-in, parallel-out shift register from Texas Instruments, part of the high-speed CMOS logic family. It features a high-speed operation, making it suitable for various digital applications. The device takes serial data input and shifts it into an 8-bit register on the leading edge of a clock signal. The stored data can then be output in parallel format.
Key features include:
- Operating voltage: 2V to 6V
- High-speed operation: up to 100 MHz at Vcc = 5V
- Low power consumption
- Compatible with standard TTL and CMOS logic levels
- Outputs can drive up to 20 mA
The SN74HC164PW is used extensively in applications such as data storage, signal processing, and LED control, providing an efficient way to manage data flow in digital circuits. Its compact 16-pin TSSOP package allows for space-saving designs in embedded systems and other electronic applications.
