Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ALS245ANSR is a bidirectional octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Bidirectional Transceiver  
- **Number of Bits:** 8  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Output Type:** 3-State  
- **Package / Case:** 20-SOIC (0.209", 5.30mm Width)  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 10ns (Max)  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 24mA  

### **Descriptions:**  
The SN74ALS245ANSR is designed for asynchronous two-way communication between data buses. It allows data transmission from A to B or B to A, depending on the direction control input. The output enable (OE) input disables both A and B ports, placing them in a high-impedance state.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR (Direction) pin  
- **3-State Outputs:** Allows bus isolation  
- **Wide Operating Voltage:** 4.5V to 5.5V  
- **High-Current Outputs:** Supports bus driving  
- **Low Power Consumption:** ALS technology for reduced power  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This device is commonly used in bus-oriented applications requiring bidirectional data transfer.
