Description and Introduction

Octal Bus Transceiver The SN74LS245 is a bidirectional octal bus transceiver manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Channels:** 8 (Octal)  
- **Supply Voltage Range (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Input High Voltage (VIH):** 2V (min)  
- **Input Low Voltage (VIL):** 0.8V (max)  
- **Output High Voltage (VOH):** 2.7V (min)  
- **Output Low Voltage (VOL):** 0.5V (max)  
- **Propagation Delay:** 15ns (max)  
- **Power Dissipation:** 80mW (typ)  

### **Description:**  
The SN74LS245 is an 8-bit bidirectional transceiver designed for asynchronous communication between data buses. It features separate input and output pins for each direction, controlled by the **Direction (DIR)** and **Output Enable (OE)** inputs.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR pin (High = A→B, Low = B→A).  
- **3-State Outputs:** Allows bus isolation when OE is high.  
- **Wide Operating Voltage:** Compatible with TTL levels.  
- **High Noise Immunity:** Typical of LS family.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Standard Pinout:** 20-pin DIP, SOIC, or other package options.
