概述

Description

The 74HC164PW is a dual 8-bit shift register that operates in parallel-in/serial-out mode. It is part of the 74HC family of high-speed CMOS logic devices and is designed for use in digital circuits requiring high-speed data processing and storage. The device has two primary modes: data can be loaded in parallel through the parallel input pins or shifted out serially through the output pins.
Key features include:
- 8-bit storage capacity
- High-speed operation with a maximum clock frequency of 25 MHz
- Low power consumption
- A single data line for serial output
- Active-high clock input and asynchronous reset
The 74HC164PW is commonly used in applications such as LED displays, data conversion, and as a basic memory element in various digital systems. Its compact packaging and ease of integration make it a popular choice for engineers and hobbyists in electronic design projects.

Features

The 74HC164PW is an 8-bit serial-in, parallel-out shift register from the 74HC family of high-speed CMOS logic. Key features include:
1. Serial Input: Data is entered serially on the DS (data input) pin.
2. Parallel Output: Provides 8 parallel outputs (Q0 to Q7), which can drive loads directly.
3. Clock Input: The shift register shifts data on the rising edge of the clock (CLK) input.
4. Asynchronous Reset: Features an active-low reset (MR) that clears the outputs when activated.
5. High Speed: Operating at high speeds up to 6 MHz, suitable for fast applications.
6. Wide Supply Voltage: Compatible with a supply voltage range of 2V to 6V.
7. Low Power Consumption: Consumes low power, making it ideal for battery-operated devices.
8. Directly Connectable: Outputs are TTL-compatible, allowing for easy interfacing with other logic families.
Overall, the 74HC164PW is widely used in digital circuits for data storage, timing applications, and LED control.

Package

The 74HC164PW is packaged in a TSSOP (Thin Shrink Small Outline Package) form factor. It features 14 pins and is designed for surface mounting, making it suitable for compact electronic applications.

Pinout

The 74HC164PW is an 8-bit serial-in, parallel-out shift register. It has 16 pins:
1. GND (Pin 1) - Ground.
2. Q1 to Q8 (Pins 2-9) - Outputs for the parallel data.
3. SER (Pin 10) - Serial data input.
4. SRCLK (Pin 11) - Shift register clock input; data shifts on the rising edge.
5. RCLK (Pin 12) - Register clock input; transfers shifted data to outputs on the rising edge.
6. MR (Pin 13) - Master reset; active low, resets all outputs to low.
7. OE (Pin 14) - Output enable; active low, enables outputs when low.
8. VCC (Pin 15) - Supply voltage.
9. NC (Pin 16) - No connection.
The 74HC164PW operates with a supply voltage range of 2V to 6V and is widely used in digital circuits for data storage and transmission applications.
