Description and Introduction

DUAL 4-INPUT AND GATE The TC74VHC21F is a dual 4-input AND gate integrated circuit manufactured by Toshiba. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Logic Type:** AND Gate  
- **Number of Gates:** 2  
- **Number of Inputs per Gate:** 4  
- **Supply Voltage Range (VCC):** 2.0V to 5.5V  
- **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 5.0V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 5.0V  
- **High-Level Output Voltage (VOH):** 4.4V (min) at VCC = 4.5V, IOH = -4mA  
- **Low-Level Output Voltage (VOL):** 0.1V (max) at VCC = 4.5V, IOL = 4mA  
- **Propagation Delay (tpd):** 5.5ns (max) at VCC = 5.0V, CL = 50pF  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-14 (Small Outline Package)  

### **Descriptions:**  
- The TC74VHC21F is a high-speed CMOS logic IC containing two independent 4-input AND gates.  
- It operates over a wide voltage range (2.0V to 5.5V), making it suitable for both 3.3V and 5V systems.  
- The device features low power consumption while maintaining high-speed operation.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Wide Operating Voltage Range:** Compatible with TTL levels at 5V.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **High Noise Immunity:** Robust against signal interference.  
- **Pb-Free Package:** Compliant with RoHS standards.
