Description and Introduction

Low-Voltage Octal Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs The TC74LCX240FK is a low-voltage CMOS octal bus buffer manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 2.0V to 3.6V  
- **High-Speed Operation:** tpd = 4.3 ns (max) at 3.3V  
- **Output Drive Capability:** ±24 mA at 3.0V  
- **Input Voltage Levels:**  
  - VIH (High-level input voltage): 2.0V (min) at VCC = 2.7V to 3.6V  
  - VIL (Low-level input voltage): 0.8V (max) at VCC = 2.7V to 3.6V  
- **Power-Down Protection:** Provided on inputs and outputs  
- **Package:** SOP20 (Small Outline Package, 20-pin)  

### **Description:**  
The TC74LCX240FK is an octal inverting buffer/line driver with 3-state outputs. It is designed for low-voltage (2.0V to 3.6V) applications while maintaining high-speed performance. The device features two active-low output enable inputs (OE1 and OE2) for independent control of the buffers.

### **Features:**  
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply  
- **3-State Outputs:** Allows bus-oriented applications  
- **High Noise Immunity:** Compliant with LVTTL/LVCMOS standards  
- **Power-Down Protection:** Prevents damage from floating inputs/outputs  
- **Pin-Compatible:** With 74 series 240-type logic devices  

This device is commonly used in digital systems requiring buffering and signal inversion in low-voltage environments.
