Description and Introduction

DECADE COUNTER; DIVIDE-BY-TWELVE COUNTER; 4-BIT BINARY COUNTER The SN74LS92N is a 4-bit ripple counter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** 4-bit ripple counter  
- **Logic Family:** LS (Low-Power Schottky)  
- **Counting Sequence:** Divide-by-2 and divide-by-6 (total divide-by-12)  
- **Operating Voltage:** 5V (standard TTL levels)  
- **Maximum Clock Frequency:** ~32 MHz (typical)  
- **Output Type:** TTL-compatible  
- **Package:** 14-pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)  

### **Descriptions:**  
- The SN74LS92N is a 4-bit asynchronous counter with a built-in divide-by-2 and divide-by-6 function, allowing it to operate as a divide-by-12 counter.  
- It consists of a master-slave flip-flop for the divide-by-2 section and three toggle flip-flops for the divide-by-6 section.  
- The counter resets to zero when both Reset inputs (R1 and R2) are high.  

### **Features:**  
- **Asynchronous Operation:** Each flip-flop triggers independently.  
- **Reset Function:** Allows the counter to be cleared via R1 and R2 inputs.  
- **High-Speed Operation:** Suitable for frequency division applications.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard TTL logic levels.  
- **Low Power Consumption:** Typical of the LS series.
