Description and Introduction

PRESETTABLE BCD/DECADE UP/DOWN COUNTER PRESETTABLE 4-BIT BINARY UP/DOWN COUNTER The SN74LS193N is a 4-bit synchronous up/down binary counter manufactured by ON Semiconductor (ON) and Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Type:** 4-bit synchronous up/down binary counter  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Counting Modes:** Up and Down  
- **Clock Inputs:** Separate up (CP↑) and down (CP↓) clock inputs  
- **Asynchronous Features:** Parallel load, clear  
- **Output Type:** TTL-compatible  
- **Package:** 16-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The SN74LS193N is a synchronous 4-bit up/down counter with individual clock inputs for counting up or down.  
- It features asynchronous parallel load and clear functionality for preset operations.  
- Synchronous counting ensures predictable operation with minimal propagation delay.  

### **Features:**  
- **Synchronous Counting:** Changes occur on clock edges for precise timing.  
- **Dual Clock Inputs:** Separate up and down clock inputs for flexible counting.  
- **Parallel Load Capability:** Allows presetting the counter value.  
- **Asynchronous Clear:** Resets the counter to zero independently of the clock.  
- **Carry and Borrow Outputs:** Facilitates cascading multiple counters.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  

This information is based solely on manufacturer datasheets for the SN74LS193N.
