Description and Introduction

50/30/100-MHz [RESETTABLE DECADE OR BINARY COUNTERS/LATCHES The SN74S197N is a 4-bit binary counter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Logic Family:** TTL (Schottky)  
- **Number of Bits:** 4  
- **Counting Sequence:** Binary  
- **Maximum Clock Frequency:** 100 MHz (typical)  
- **Propagation Delay:** 10 ns (typical)  
- **Power Dissipation:** 500 mW (max)  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 16  

### **Descriptions:**  
The SN74S197N is a high-speed 4-bit synchronous binary counter with asynchronous clear functionality. It is designed for use in digital counting applications where fast operation and reliable performance are required. The counter can be preset to a specific value using parallel load inputs and features ripple carry output for cascading multiple counters.  

### **Features:**  
- **Synchronous Counting:** Operates with a common clock signal.  
- **Asynchronous Clear:** Resets the counter to zero independently of the clock.  
- **Parallel Load Capability:** Allows preset values to be loaded via data inputs.  
- **Ripple Carry Output:** Facilitates cascading of multiple counters.  
- **High-Speed Operation:** Suitable for fast digital systems.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Wide Operating Voltage Range:** Supports standard 5V power supply.  

This information is strictly factual and derived from Ic-phoenix technical data files.
