Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74HCT245DBR 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)  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8 (Octal)  
- **Input Type:** Schmitt Trigger
