Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Dual Binary Counter The TC74AC393F is a dual 4-bit binary counter manufactured by Toshiba. Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Dual 4-bit Binary Counter  
- **Logic Family:** AC (Advanced CMOS)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** 4.5ns (typical) at 5V  
- **Low Power Consumption:** 4μA (max) at 5V  
- **Output Current:** ±24mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOP-14 (Small Outline Package)  

### **Descriptions:**  
- The TC74AC393F consists of two independent 4-bit binary counters with separate clock inputs and reset functions.  
- Each counter can be used individually or cascaded for higher-bit counting applications.  
- It operates over a wide voltage range, making it suitable for both 3.3V and 5V systems.  

### **Features:**  
- **Dual Counter Design:** Two separate 4-bit counters in one package.  
- **Asynchronous Reset:** Each counter has a clear (reset) input.  
- **High-Speed CMOS Technology:** Ensures fast operation with low power consumption.  
- **Wide Operating Voltage:** Compatible with TTL levels.  
- **Schmitt Trigger Inputs:** Provides noise immunity on clock inputs.  
- **Balanced Propagation Delays:** Ensures reliable performance in counting applications.  

This information is based on Toshiba's official documentation for the TC74AC393F.
