Description and Introduction

Synchronous 4-Bit Binary Counters The SN74ALS163BN is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Binary Counter  
- **Counting Method:** Fully Synchronous  
- **Operating Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  
- **Clock Frequency:** Typically up to 32 MHz  
- **Output Type:** Standard  
- **Propagation Delay:** 15 ns (max)  
- **Supply Current:** 8 mA (max)  
- **Load Capacitance:** 50 pF  

### **Descriptions and Features:**  
- **Synchronous Operation:** All flip-flops are clocked simultaneously, ensuring predictable timing.  
- **Parallel Load Capability:** Allows loading of a preset value into the counter.  
- **Clear Function:** Asynchronous master reset (MR) clears all flip-flops.  
- **Carry Look-Ahead:** Enables high-speed counting by generating a carry output for cascading multiple counters.  
- **Fully Programmable:** Can be preset to any value between 0 and 15 (binary).  
- **Applications:** Used in frequency division, timing circuits, and digital counting systems.  

This device is part of TI's ALS (Advanced Low-Power Schottky) logic family, offering a balance of speed and power efficiency.
