Description and Introduction

OCTAL BUS BUFFER WITH TTL INPUT LEVEL. INVERTED/NON-INVERTED, 3-STATE OUTPUTS The TC74HCT244AFW is an octal bus buffer manufactured by Toshiba. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL compatible)  
- **Number of Channels:** 8 (Octal)  
- **Input Voltage (High):** 2.0V (min)  
- **Input Voltage (Low):** 0.8V (max)  
- **Output Voltage (High):** 4.4V (min at VCC = 4.5V, IOH = -4mA)  
- **Output Voltage (Low):** 0.33V (max at VCC = 4.5V, IOL = 4mA)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Propagation Delay:** 16ns (max at VCC = 4.5V, CL = 50pF)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74HCT244AFW is a non-inverting octal buffer/line driver with 3-state outputs.  
- It is designed for bus-oriented applications, allowing bidirectional data flow when used in pairs.  
- The device features two active-low output enable pins (OE1 and OE2) that control four buffers each.  

### **Features:**  
- **TTL-Compatible Inputs:** Can interface directly with TTL levels.  
- **3-State Outputs:** Allows multiple devices to share a common bus without interference.  
- **High-Speed Operation:** Suitable for high-performance digital systems.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  

This information is based solely on Toshiba's datasheet for the TC74HCT244AFW.
