Description and Introduction

OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS The SN74HCT244DB is a high-speed CMOS logic octal buffer and line driver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Technology:** High-Speed CMOS (HCT)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Logic Family:** HCT (TTL-compatible CMOS)  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** 3-State (Tri-State)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DB) – 20-pin  
- **Input/Output Compatibility:** TTL-Level Inputs, CMOS Outputs  
- **Propagation Delay:** Typically 13 ns at 5V  
- **Output Drive Capability:** ±6 mA  

### **Descriptions and Features:**  
- **Function:** The SN74HCT244DB is an octal buffer and line driver designed to improve bus driving capability while maintaining signal integrity.  
- **3-State Outputs:** Allows outputs to be disabled (high-impedance state) for bus-oriented applications.  
- **TTL-Compatible Inputs:** Works with TTL logic levels (0.8V LOW, 2.0V HIGH).  
- **Balanced Propagation Delays:** Ensures synchronized signal transmission.  
- **Low Power Consumption:** Typical ICC of 80 µA.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

### **Applications:**  
- Bus buffering and driving  
- Memory address driving  
- Data transmission systems  
- General-purpose logic level shifting
