概要

Description

The 74HC164D is an 8-bit serial-in, parallel-out shift register, part of the 74HC family of high-speed CMOS logic devices. It is designed to convert serial data input into parallel data output, making it useful for data storage and transfer applications. The device features a serial data input (DS), a clock input (CLK), and eight parallel output pins (Q0 to Q7).
When a clock pulse is applied, the 74HC164D shifts the serial input data into the register, allowing data to be captured one bit at a time. Once the desired number of bits is entered, the outputs can be accessed simultaneously, enabling efficient data manipulation and transfer.
Key features include:
- Wide operating voltage range (2V to 6V)
- High-speed operation (up to 25 MHz)
- Low power consumption
- TTL-compatible inputs and outputs
The 74HC164D is commonly used in applications such as LED displays, data communication systems, and microcontroller interfacing, making it a versatile component in digital circuits.

Features

The 74HC164D is a high-speed CMOS shift register that features:
1. 8-Bit Serial-In, Parallel-Out: It allows data to be shifted in serially and output in parallel.
2. Dual Supply Voltage: Compatible with 2V to 6V logic levels, making it versatile for various applications.
3. Low Power Consumption: Efficient operation with reduced power usage compared to other families.
4. High-Speed Operation: Capable of operating at frequencies up to 20 MHz at VCC = 5V.
5. Asynchronous Reset: Offers a reset function that clears the register to a known state.
6. Data Propagation Delay: Short delay times for fast data processing.
7. Pin Compatible: Typically available in 16-pin DIP and SOP packages, facilitating easy integration into circuits.
8. Wide Range of Applications: Useful in LED displays, data storage, and digital systems requiring parallel data outputs.
These features make the 74HC164D suitable for various digital applications, including serial communication and data manipulation tasks.

Package

Pinout

The 74HC164D is an 8-bit serial-in, parallel-out shift register. It features a total of 16 pins:
1. Pins 1, 2, 3, 4, 5, 6, 7, 8 (Q0 to Q7): Parallel output pins that provide the shifted data.
2. Pin 9 (GND): Ground connection.
3. Pin 10 (CLR): Asynchronous clear input that resets the register.
4. Pin 11 (DS): Serial data input for shifting data into the register.
5. Pin 12 (STROBE): Clock input that shifts data on the rising edge.
6. Pin 13 (Q7'): Serial output, provides the last bit shifted out.
7. Pin 14 (VCC): Power supply connection.
8. Pins 15, 16 (NC): No connect (not used).
The device allows data to be shifted into the register serially, which can then be accessed in parallel form. The 74HC164D operates at high speeds and is suitable for various digital applications.
