Description and Introduction

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS The SN74LS162N is a synchronous 4-bit decade counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous Decade Counter  
- **Number of Bits:** 4  
- **Counting Sequence:** 0 to 9 (Decade)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-16 (Plastic Dual In-Line Package)  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Propagation Delay:** 20 ns (max)  
- **Output Type:** TTL (Transistor-Transistor Logic)  
- **Features Synchronous Counting:** All flip-flops change state simultaneously  
- **Parallel Load Capability:** Allows presetting the counter  
- **Clear Input:** Asynchronous master reset  
- **Carry Output:** Enables cascading multiple counters  

### **Descriptions and Features:**  
- The SN74LS162N is a synchronous 4-bit decade counter with a built-in look-ahead carry for high-speed counting applications.  
- It operates synchronously, meaning all flip-flops are clocked simultaneously, avoiding ripple delays.  
- Includes parallel load capability for presetting the counter to a desired value.  
- Features an asynchronous master reset (clear) to force the counter to zero.  
- The carry output (RCO) facilitates cascading multiple counters for higher-bit applications.  
- Designed for use in counting, frequency division, and timing applications.  
- Compatible with standard TTL logic levels.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and timing diagrams, refer to TI's official documentation.
