Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74HCT245N is a high-speed CMOS logic octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Number of Channels:** 8  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage (High Level):** 2V (min)  
- **Input Voltage (Low Level):** 0.8V (max)  
- **Output Current (High/Low):** ±6mA  
- **Propagation Delay:** 14ns (typical at 5V)  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 20  

### **Descriptions and Features:**  
- **Bidirectional Voltage-Level Translation:** Allows interfacing between 5V and lower voltage systems.  
- **3-State Outputs:** Supports bus-oriented applications.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **Non-Inverting Data Paths:** Maintains signal integrity.  
- **Direction Control (DIR Pin):** Determines data flow direction (A to B or B to A).  
- **Output Enable (OE Pin):** Disables outputs when high, allowing bus isolation.  
- **Low Power Consumption:** Typical ICC of 80µA (static).  
- **ESD Protection:** Exceeds 2000V (HBM) for reliability.  

This device is commonly used in data communication, buffering, and level-shifting applications.
