Description and Introduction

PRESETTABLE BCD/DECADE UP/DOWN COUNTER PRESETTABLE 4-BIT BINARY UP/DOWN COUNTER The SN74LS193D is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Counter Type:** Synchronous 4-bit up/down binary counter  
- **Operating Voltage:** 4.75V to 5.25V  
- **Clock Frequency:** Up to 25 MHz  
- **Propagation Delay:** Typically 15 ns  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC (Small Outline Integrated Circuit)  
- **Pin Count:** 16  

### **Descriptions:**  
- The SN74LS193D is a synchronous counter with separate up and down clock inputs, allowing bidirectional counting.  
- It features a parallel load capability for presetting the counter value.  
- Includes carry and borrow outputs for cascading multiple counters.  
- Fully synchronous operation ensures predictable counting behavior.  

### **Features:**  
- **Synchronous Counting:** All flip-flops change state simultaneously.  
- **Parallel Load Input:** Allows loading a preset value via data inputs.  
- **Up/Down Counting:** Separate clock inputs for incrementing or decrementing.  
- **Carry & Borrow Outputs:** Facilitates cascading multiple counters.  
- **Asynchronous Clear:** Resets the counter to zero independently of the clock.  
- **Wide Operating Voltage Range:** Compatible with standard 5V TTL logic.  

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