Description and Introduction

Synchronous 4-Bit Up/Down Binary Counters With Dual Clock and Clear The SN74LS193NSR is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Up/Down Binary Counter  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-16  
- **Counting Sequence:** Binary  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Output Type:** Standard  

### **Descriptions:**  
The SN74LS193NSR is a high-speed synchronous counter with individual preset inputs, allowing for parallel loading. It features separate up and down clock inputs for bidirectional counting.  

### **Features:**  
- Synchronous counting and loading  
- Asynchronous master reset  
- Carry and borrow outputs for cascading  
- Parallel load capability  
- Fully independent clock inputs for up/down counting  
- Low power consumption (LS technology)  

This information is based on the manufacturer's datasheet.
