概述

Description

The 74HCT164D is an 8-bit serial-in, parallel-out shift register, part of the 74HCT family of digital logic components. It operates with a supply voltage range of 2V to 6V and is designed for high-speed operations, making it compatible with TTL (Transistor-Transistor Logic) levels.
The device features a serial data input (DS), clock input (CLK), and an asynchronous active-low reset (MR) that resets the output to zero. Upon each clock pulse, the data at the serial input is shifted into the register, allowing for data storage and manipulation. The outputs (Q0 to Q7) can be accessed simultaneously in parallel, making it useful for applications such as data communication, LED driving, and digital signal processing.
The 74HCT164D is widely used in digital circuits for tasks like data transfer, temporary data storage, and control signal generation in various electronic applications. Its versatility, coupled with ease of use, makes it a popular choice among engineers and hobbyists.

Features

The 74HCT164D is an 8-bit serial-in/parallel-out shift register with a specific focus on high-speed operation and low power consumption. Key features include:
1. 8-Bit Shift Register: It can shift in data serially and output it in parallel.
2. High-Speed Operation: Typically operates at speeds up to 25 MHz.
3. Low Power: Designed with TTL compatibility, it consumes less power compared to traditional TTL devices.
4. Serial Data Input: Data can be loaded in serially via a single input pin.
5. Parallel Outputs: Eight output pins provide the parallel data.
6. Clock Input: Shifts data on the rising edge of the clock signal.
7. Reset Function: Includes an asynchronous reset to clear the output registers.
8. TTL Compatibility: Compatible with standard TTL logic levels.
9. Wide Supply Voltage Range: Operates from a supply voltage of 4.5V to 5.5V.
This makes the 74HCT164D suitable for applications in digital systems requiring data manipulation and storage.
