Description and Introduction

TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC The TC74HC244 is a high-speed CMOS octal bus buffer manufactured by Toshiba. It is designed for 2V to 6V operation and features 3-state outputs.  

### **Specifications:**  
- **Logic Family:** HC (High-speed CMOS)  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **Input Voltage Range (VI):** 0V to VCC  
- **Output Voltage Range (VO):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **High-Level Input Voltage (VIH):** 2V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 4.5V  
- **High-Level Output Current (IOH):** -5.2mA (min) at VCC = 4.5V  
- **Low-Level Output Current (IOL):** 5.2mA (min) at VCC = 4.5V  
- **Propagation Delay (tpd):** 14ns (max) at VCC = 4.5V  
- **Output Configuration:** 3-state (non-inverting)  
- **Package Options:** SOP-20, TSSOP-20  

### **Descriptions:**  
- The TC74HC244 is an octal buffer/line driver with 3-state outputs.  
- It is designed to improve bus driving capability in digital systems.  
- The device has two active-low output enable pins (OE1, OE2), each controlling four buffers.  

### **Features:**  
- **High-Speed Operation:** Comparable to LSTTL with low power consumption.  
- **Wide Operating Voltage:** 2V to 6V.  
- **High Output Current:** Capable of driving up to 5.2mA.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Balanced Propagation Delays:** Ensures reliable signal timing.  
- **Low Power Consumption:** Typical ICC = 4μA (max) at 25°C.  
- **ESD Protection:** HBM ≥ 2000V.  

This information is based on Toshiba's datasheet for the TC74HC244.
