Description and Introduction

OCTAL BUS TRANSCEIVER The SN54LS245 is a bus transceiver manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Technology:** TTL (Transistor-Transistor Logic)  
- **Number of Channels:** 8-bit bidirectional  
- **Operating Voltage:** 4.5V to 5.5V  
- **High-Level Output Current:** -2.6 mA  
- **Low-Level Output Current:** 24 mA  
- **Propagation Delay:** Typically 15 ns  
- **Operating Temperature Range (SN54):** -55°C to +125°C (Military grade)  
- **Package Options:** Ceramic DIP (Dual In-line Package)  

### **Descriptions:**  
The SN54LS245 is an octal bus transceiver designed for bidirectional communication between data buses. It features separate control inputs for direction (DIR) and output enable (G̅).  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **High-Current Outputs:** Capable of driving heavily loaded buses.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  
- **Low Power Consumption:** Typical of LS TTL technology.  

This information is based on the manufacturer's datasheet for the SN54LS245.
