Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SNJ54HCT244J is a high-speed CMOS logic octal buffer/line driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Number of Channels:** 8 (Octal)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage (High Level - VIH):** 2V (min)  
- **Input Voltage (Low Level - VIL):** 0.8V (max)  
- **Output Current (High - IOH):** -6mA  
- **Output Current (Low - IOL):** 6mA  
- **Propagation Delay:** 13ns (typical)  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** Ceramic DIP (Dual In-Line Package)  
- **Pin Count:** 20  

### **Descriptions:**  
- The SNJ54HCT244J is a non-inverting octal buffer/line driver with 3-state outputs.  
- Designed for bus-oriented applications, it provides high drive capability.  
- Compatible with TTL inputs, making it suitable for mixed-voltage systems.  
- Features two active-low output enable inputs for independent control of the 4-bit sections.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system without bus contention.  
- **High Noise Immunity:** Typical CMOS noise margin of 1V at VCC = 5V.  
- **Balanced Propagation Delays:** Ensures consistent signal timing.  
- **Low Power Consumption:** Typical ICC of 80µA.  
- **Military Temperature Range:** Suitable for harsh environments.  

This device is commonly used in digital systems requiring buffering, signal isolation, or bus driving.
