Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74HCT245 is a high-speed CMOS logic octal bus transceiver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Number of Channels:** 8 (Octal)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage Levels:** TTL-Compatible (0.8V max for LOW, 2V min for HIGH)  
- **Output Drive Capability:** ±6mA at 5V  
- **Propagation Delay:** Typically 13ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOIC, TSSOP, PDIP  

### **Description:**  
The SN74HCT245 is an 8-bit bidirectional transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is commonly used for bus interfacing in digital systems.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR (Direction) input  
- **3-State Outputs:** Allows bus isolation when OE (Output Enable) is high  
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels  
- **Low Power Consumption:** Typical ICC of 80µA  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This device is widely used in applications such as data buffering, bus isolation, and level translation.
