Description and Introduction

OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS The SN74HC244DB is an octal buffer and line driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Channels:** 8 (Octal)  
- **Input Type:** CMOS  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Output Current:** -7.8mA  
- **Low-Level Output Current:** 7.8mA  
- **Propagation Delay Time:** 12ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP-20  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74HC244DB is a high-speed CMOS logic device designed to drive bus lines or buffer memory address registers. It features non-inverting outputs and separate output-enable (OE) inputs for each 4-bit section, allowing for flexible control.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus-oriented system.  
- **Balanced Propagation Delays:** Ensures consistent signal timing.  
- **Wide Operating Voltage Range:** 2V to 6V.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **High Noise Immunity:** Typical of CMOS devices.  
- **ESD Protection:** Exceeds JESD 22 standards (2000V HBM, 200V MM).  

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