Description and Introduction

Synchronous 4-Bit Binary Counters Here are the factual details about the **SN74AS161NSR** from the manufacturer Texas Instruments (TI):

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN74AS161NSR  
- **Type:** 4-Bit Synchronous Binary Counter  
- **Logic Family:** AS (Advanced Schottky)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC (Small Outline Integrated Circuit)  
- **Number of Pins:** 16  
- **Counting Sequence:** Binary (0000 to 1111)  
- **Clock Frequency (Max):** 100 MHz (typical)  
- **Propagation Delay (Max):** 9 ns (typical)  
- **Output Type:** TTL-Compatible  

### **Descriptions:**
The **SN74AS161NSR** is a synchronous 4-bit binary counter with a direct clear input. It features fully synchronous operation, meaning the outputs change state only in response to a clock pulse. The counter can be preset in parallel or cleared asynchronously. It is designed for high-speed counting applications in digital systems.

### **Features:**
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Parallel Load Capability:** Allows for preset inputs.  
- **Asynchronous Clear:** Resets the counter to zero independently of the clock.  
- **Carry Output:** Provides ripple carry for cascading counters.  
- **High-Speed Operation:** Optimized for fast counting applications.  
- **Low Power Consumption:** Compared to standard TTL logic.  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with other logic families.
