series introduction

# Introduction to the PHS74HC4067 Product Series

## 1. Overview
The PHS74HC4067 is a highly versatile and widely - used integrated circuit belonging to the 74HC series. It is a 16 - channel analog multiplexer/demultiplexer, designed to provide efficient signal routing and selection capabilities in a variety of electronic systems. This product series combines the advantages of high - speed CMOS technology with the functionality of a multi - channel switch, making it suitable for applications that require the management of multiple analog or digital signals.

## 2. Key Features

### 2.1 High - Speed Operation
Based on high - speed CMOS technology, the PHS74HC4067 offers fast switching times. This allows for rapid signal routing, which is crucial in applications where real - time data processing or high - frequency signal handling is required. The high - speed operation ensures that there is minimal delay in signal transmission, enabling smooth and efficient system performance.

### 2.2 Low Power Consumption
One of the significant advantages of the PHS74HC4067 is its low power consumption. CMOS technology inherently consumes less power compared to other logic families, making this device ideal for battery - powered applications or systems where power efficiency is a priority. This not only helps in reducing the overall energy consumption of the system but also extends the battery life in portable devices.

### 2.3 Wide Supply Voltage Range
The PHS74HC4067 can operate over a wide supply voltage range, typically from 2V to 6V. This flexibility allows it to be easily integrated into different electronic systems with varying power supply requirements. Whether it is a low - voltage microcontroller - based system or a standard 5V logic circuit, the PHS74HC4067 can adapt and function effectively.

### 2.4 16 - Channel Configuration
With 16 input/output channels, the PHS74HC4067 provides a high - density solution for signal routing. It can select one of the 16 input channels and connect it to the common output (in multiplexer mode) or route a single input signal to one of the 16 output channels (in demultiplexer mode). This large number of channels makes it suitable for applications that involve multiple sensors, actuators, or data sources.

### 2.5 TTL - Compatible Inputs
The inputs of the PHS74HC4067 are TTL - compatible, which means they can interface directly with TTL - level logic signals. This simplifies the design process when integrating the device into existing TTL - based systems, as there is no need for additional level - shifting circuitry.

## 3. Functional Description

### 3.1 Multiplexer Mode
In multiplexer mode, the PHS74HC4067 selects one of the 16 input channels (D0 - D15) and connects it to the common output (Y). The selection of the input channel is controlled by four address lines (A0 - A3). Each unique combination of the address line states corresponds to a specific input channel. For example, when A0 = 0, A1 = 0, A2 = 0, and A3 = 0, input channel D0 is selected and connected to the output Y.

### 3.2 Demultiplexer Mode
In demultiplexer mode, the operation is reversed. A single input signal applied to the common input (Y) is routed to one of the 16 output channels (D0 - D15) based on the states of the four address lines (A0 - A3). This mode is useful in applications where a single signal needs to be distributed to multiple destinations
