Description and Introduction

OCTAL BUS TRANSCEIVERS The SN74LS621N is a 20-pin DIP (Dual Inline Package) octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 8 (Octal)  
- **Direction Control:** Bidirectional  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Input/Output Compatibility:** TTL (Transistor-Transistor Logic)  
- **Propagation Delay:** Typically 15ns  
- **Output Current (High/Low):** ±2.6mA / 24mA  
- **Package Type:** PDIP (Plastic Dual Inline Package)  

### **Description:**  
The SN74LS621N is an octal bus transceiver designed for bidirectional data transfer between two buses. It features separate input and output controls for each direction, allowing flexible data flow management.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR (Direction) input.  
- **Independent Enable Inputs:** OE (Output Enable) for each bus.  
- **Low Power Consumption:** Typical of LS series.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard TTL logic.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  

This device is commonly used in microprocessor and digital systems for bus interfacing.
