Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SNJ54HC244FK is a high-speed CMOS logic octal buffer and line driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Technology:** High-Speed CMOS (HC)  
- **Logic Family:** HC  
- **Number of Channels:** 8 (Octal)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Output Current:** ±6mA at 5V  
- **Propagation Delay:** 13 ns (typical at 5V)  
- **Input Capacitance:** 3.5 pF (typical)  
- **Package Type:** Ceramic Flatpack (FK)  

### **Descriptions:**
- The SNJ54HC244FK is a non-inverting octal buffer and line driver with 3-state outputs.  
- Designed for bus-oriented applications, it can drive high-capacitance loads with improved speed and power efficiency.  
- The device features two active-low output enable inputs (OE1 and OE2), each controlling four buffers.  
- It is part of TI’s military-grade (54-series) HC family, ensuring reliability in harsh environments.  

### **Features:**
- **Non-Inverting Buffers:** Maintains signal polarity.  
- **3-State Outputs:** Allows for bus sharing and isolation.  
- **Wide Operating Voltage:** 2V to 6V.  
- **High Noise Immunity:** Typical CMOS noise margin.  
- **Balanced Propagation Delays:** Ensures signal integrity.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Military Temperature Range:** Suitable for aerospace and defense applications.  

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