Description and Introduction

OCTAL BUS TRANSCEIVER (3 STATE INVERTING) The M74HC620B1R is a high-speed CMOS octal bus transceiver with 3-state outputs, manufactured by SGS (now part of STMicroelectronics).  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Function:** Bus Transceiver  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Propagation Delay:** Typically 13 ns at 5V  
- **Input/Output Compatibility:** TTL Levels  
- **Package Type:** SO-20 (Small Outline)  

### **Descriptions and Features:**  
- **Bidirectional Data Flow:** Allows data transmission in both directions (A to B or B to A).  
- **3-State Outputs:** Supports high-impedance state for bus-oriented applications.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Improved noise margins compared to standard CMOS.  
- **Wide Operating Voltage:** Compatible with 2V to 6V systems.  
- **Common Enable Inputs:** Two control pins (GAB, GBA) for direction selection.  

This IC is commonly used in data bus interfacing, buffering, and bidirectional communication in digital systems.
