Description and Introduction

Low-Voltage Hex Schmitt Inverter with 5-V Tolerant Inputs and Outputs The TC74LCX14FK is a hex inverter with Schmitt-trigger inputs, manufactured by Toshiba. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Family:** LCX (Low Voltage CMOS)  
- **Number of Inverters:** 6 (Hex)  
- **Input Type:** Schmitt-trigger  
- **Supply Voltage Range (VCC):** 2.0V to 3.6V  
- **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 3.0V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 3.0V  
- **High-Level Output Voltage (VOH):** 2.4V (min) at VCC = 3.0V, IOH = -24mA  
- **Low-Level Output Voltage (VOL):** 0.4V (max) at VCC = 3.0V, IOL = 24mA  
- **Propagation Delay (tPD):** 5.5ns (max) at VCC = 3.3V, CL = 50pF  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (Shrink Small Outline Package)  
- **Pin Count:** 14  

### **Descriptions:**  
- The TC74LCX14FK is a hex Schmitt-trigger inverter IC designed for low-voltage operation (2.0V to 3.6V).  
- It features hysteresis on the inputs, making it suitable for noise filtering and signal conditioning.  
- The device is compatible with TTL levels and supports high-speed operation.  

### **Features:**  
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply.  
- **High Noise Immunity:** Schmitt-trigger inputs provide hysteresis for improved noise rejection.  
- **High-Speed Performance:** Typical propagation delay of 5.5ns at 3.3V.  
- **High Drive Capability:** Supports ±24mA output current.  
- **TTL-Compatible Inputs:** Can interface with 5V TTL levels.  
- **Power-Down Protection:** Inputs and outputs include protection against damage when VCC = 0V.  
- **SSOP Package:** Compact surface-mount package for space-saving designs.  

This information is strictly factual and derived from Toshiba's datasheet for the TC74LCX14FK.
