Description and Introduction

Octal Bus Transceivers With 3-State Outputs Here are the factual details about the **SN74ALS245AN** from the manufacturer **Texas Instruments (TI)**:

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** SN74ALS245AN  

### **Specifications:**  
- **Logic Family:** ALS (Advanced Low-Power Schottky)  
- **Logic Type:** Octal Bus Transceiver  
- **Number of Channels:** 8 (Octal)  
- **Input/Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** PDIP (Plastic Dual-In-Line Package)  
- **Pin Count:** 20  
- **Direction Control:** Yes (DIR pin for bidirectional operation)  
- **Output Current (High/Low):** ±15mA / 24mA  
- **Propagation Delay (Max):** 12ns (typical)  
- **High-Level Input Voltage (Min):** 2.0V  
- **Low-Level Input Voltage (Max):** 0.8V  

### **Description:**  
The **SN74ALS245AN** is an octal bus transceiver designed for bidirectional asynchronous communication between data buses. It features 3-state outputs that allow multiple devices to share a common bus. The direction of data flow is controlled by the **DIR** (Direction) input, while the **OE** (Output Enable) input disables the outputs when high.  

### **Features:**  
- **Bidirectional Data Flow** controlled by DIR pin  
- **3-State Outputs** for bus-oriented applications  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **Low Power Consumption** (ALS technology)  
- **High-Speed Operation** (12ns max propagation delay)  
- **ESD Protection** on all inputs and outputs  
- **Standard 20-Pin DIP Package**  

This information is based on Texas Instruments' official documentation for the **SN74ALS245AN**.
