Description and Introduction

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS The SN74LS163N is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Type:** Synchronous 4-Bit Binary Counter  
- **Operating Voltage:** 4.75V to 5.25V  
- **Clock Frequency:** Up to 32 MHz  
- **Count Sequence:** Binary (0000 to 1111)  
- **Reset:** Synchronous (requires clock pulse)  
- **Load Capability:** Parallel load input  
- **Output Type:** Standard (TTL-compatible)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Pin DIP (Dual In-line Package)  

### **Descriptions:**  
The SN74LS163N is a fully synchronous 4-bit binary counter with parallel load and synchronous clear. It counts on the rising edge of the clock signal and features synchronous operation, meaning outputs change only on the clock pulse.  

### **Features:**  
- Synchronous counting and loading  
- Parallel load capability  
- Synchronous clear (reset)  
- Carry output for cascading counters  
- TTL-compatible inputs and outputs  
- Low power consumption (typical 45 mW)  

This device is commonly used in digital counting applications, frequency dividers, and sequential logic circuits.

Description and Introduction

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS The SN74LS163N is a synchronous 4-bit binary counter manufactured by AMD (Advanced Micro Devices).  

### **Specifications:**  
- **Type:** Synchronous 4-bit binary counter  
- **Logic Family:** LS (Low-Power Schottky)  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-pin DIP (Dual In-line Package)  
- **Counting Modes:** Synchronous (parallel load, clear, and count operations)  
- **Clock Input:** Positive-edge triggered  
- **Output Type:** TTL-compatible  

### **Descriptions and Features:**  
- **Synchronous Operation:** All flip-flops are clocked simultaneously.  
- **Parallel Load Capability:** Allows loading of a preset value.  
- **Clear Function:** Resets the counter to zero.  
- **Carry Output:** Provides cascading capability for higher-bit counters.  
- **Internal Look-Ahead:** Improves counting speed.  
- **Applications:** Frequency division, timing circuits, digital counters.  

This information is based on the manufacturer's datasheet.
