Description and Introduction

SYNCHRONOUS 4-BIT DECADE AND BINARY COUNTERS The SN74AS163DR is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Binary Counter  
- **Family:** AS (Advanced Schottky)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  
- **Count Frequency:** Up to 100MHz (typical)  
- **Number of Bits:** 4  
- **Reset Type:** Synchronous  
- **Trigger Type:** Positive Edge  
- **Propagation Delay Time:** 9ns (typical)  
- **Output Type:** Standard  

### **Descriptions:**  
- The SN74AS163DR is a synchronous, presettable 4-bit binary counter with a synchronous clear.  
- It features parallel load capability for programmable counting.  
- Synchronous operation ensures predictable timing and avoids counting errors.  
- The device operates on a single 5V power supply.  

### **Features:**  
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Parallel Load:** Allows loading of any 4-bit binary number.  
- **Synchronous Clear:** Resets all flip-flops on the next clock edge.  
- **Carry Output:** Enables cascading of multiple counters.  
- **High-Speed Operation:** Optimized for fast counting applications.  
- **Low Power Consumption:** Advanced Schottky technology reduces power dissipation.
