Description and Introduction

5V ECL 5-Bit Differential Register The MC100E452FNR2 is a high-speed ECL (Emitter-Coupled Logic) device manufactured by **ON Semiconductor** (formerly part of Motorola's semiconductor division, hence the "MOT" designation).  

### **Key Specifications:**  
- **Logic Family:** ECL (10KH Series)  
- **Function:** 8-Bit Synchronous Binary Up Counter  
- **Supply Voltage (VEE):** -5.2V (standard ECL power supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead PLCC (Plastic Leaded Chip Carrier)  
- **Speed:** High-performance ECL, suitable for >1 GHz applications  
- **Output Type:** Differential ECL  

### **Features:**  
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Master Reset (MR):** Asynchronous reset for clearing the counter.  
- **Carry Output (RCO):** Provides ripple carry for cascading multiple counters.  
- **ECL Compatibility:** Fully compatible with 10K/100K ECL logic families.  
- **Low Skew:** Designed for minimal propagation delay variation.  

### **Applications:**  
- High-speed counting in telecommunications and networking.  
- Clock distribution and frequency synthesis.  
- Military and aerospace systems requiring ECL reliability.  

This part is **obsolete** (no longer in production) but may still be available through distributors specializing in legacy components.

Application Scenarios & Design Considerations

5V ECL 5-Bit Differential Register

Alternative Part Number

  • SY100E452JY --: Pin-compatible ECL differential register in the same 100E logic family, available in PLCC package and widely used as a direct replacement.
  • MC10E452FNG --: Same ECL 100E-series function from the successor of Motorola, offered in lead-free PLCC and electrically equivalent to the original.
  • SY10E452JC --: 10E-series ECL differential register with matching logic function and PLCC footprint, suitable as a functional drop-in alternative.
