Description and Introduction

Bi-Quinary Counter The MC10138P is a high-speed ECL (Emitter-Coupled Logic) 4-bit magnitude comparator manufactured by Motorola (MOT).  

### **Manufacturer Specifications (MOT):**  
- **Logic Family:** ECL (10H Series)  
- **Function:** 4-bit magnitude comparator  
- **Operating Voltage:** -5.2V (standard ECL power supply)  
- **Propagation Delay:** Typically 2.5 ns (high-speed operation)  
- **Power Dissipation:** ~275 mW (typical)  
- **Operating Temperature Range:** 0°C to +75°C  
- **Package Type:** 16-pin DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- Compares two 4-bit binary or BCD numbers (A3-A0 and B3-B0).  
- Provides three output signals: **A > B**, **A = B**, and **A < B**.  
- Fully compatible with other ECL 10K/10H series logic.  
- High-speed operation suitable for arithmetic and control applications.  
- Cascadable for larger word comparisons.  
- Internal input pull-down resistors for unused inputs.  

The MC10138P is designed for high-performance digital systems requiring fast comparison operations.
