Description and Introduction

DECADE COUNTER; DIVIDE-BY-TWELVE COUNTER; 4-BIT BINARY COUNTER The SN74LS93N is a 4-bit binary counter manufactured by Motorola (MOT). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Motorola (MOT)  
- **Logic Family:** 74LS (Low-Power Schottky)  
- **Function:** 4-bit binary counter  
- **Counting Sequence:** Asynchronous (ripple counter)  
- **Operating Voltage:** 4.75V to 5.25V (standard 5V operation)  
- **Maximum Clock Frequency:** ~35 MHz (typical)  
- **Output Type:** TTL (Transistor-Transistor Logic) compatible  
- **Number of Pins:** 14 (DIP package)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  

### **Descriptions:**  
- The SN74LS93N consists of four master-slave JK flip-flops internally connected to provide a divide-by-2 counter and a divide-by-8 counter.  
- It can be configured as a 4-bit ripple counter (modulo-16) by connecting the Q0 output to the CLK B input.  
- The counter resets to zero when both Reset inputs (R1 and R2) are high.  

### **Features:**  
- **Independent Divide-by-2 and Divide-by-8 Counters:** Can be used separately or cascaded.  
- **Asynchronous Reset:** Clears the counter outputs when both R1 and R2 are high.  
- **Low Power Consumption:** Typical power dissipation of 45 mW.  
- **Wide Operating Voltage:** Compatible with standard TTL logic levels.  
- **Standard 14-Pin DIP Package:** Easy to integrate into breadboards and PCBs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
