Description and Introduction

TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC The TC74HC157AFN is a high-speed CMOS quad 2-input multiplexer manufactured by Toshiba. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Input Voltage Range:** 0V to VCC  
- **High-Level Output Current:** -5.2mA (min)  
- **Low-Level Output Current:** 5.2mA (min)  
- **Propagation Delay Time:** 13ns (max) at VCC = 4.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin plastic DIP (FN)  

### **Descriptions:**  
- The TC74HC157AFN is a quad 2-input multiplexer that selects one of two data sources based on the select input.  
- It is designed for high-speed operation while maintaining low power consumption.  
- Suitable for data routing, signal selection, and bus switching applications.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it versatile for different logic levels.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **High Noise Immunity:** Robust against electrical noise.  

This information is based on Toshiba's datasheet for the TC74HC157AFN.
