Description and Introduction

Look-Ahead Carry Block The MC10H179L is a high-speed ECL (Emitter-Coupled Logic) device manufactured by **MOT (Motorola)**.  

### **Specifications:**  
- **Logic Family:** ECL 10H  
- **Function:** 9-bit odd/even parity generator/checker  
- **Operating Voltage:** -5.2V (standard ECL power supply)  
- **Propagation Delay:** Typically **1.5 ns** (high-speed operation)  
- **Power Dissipation:** Approximately **500 mW** (varies with operating conditions)  
- **Temperature Range:** **0°C to +75°C** (commercial grade)  
- **Package Type:** 20-pin ceramic DIP (Dual In-line Package)  

### **Descriptions and Features:**  
- **9-bit Parity Processing:** Capable of generating or checking parity for 9-bit data words.  
- **Odd/Even Parity Selection:** Configurable for either odd or even parity operations.  
- **High-Speed Operation:** Optimized for ECL systems requiring fast signal processing.  
- **ECL Compatibility:** Designed for integration with other ECL logic families.  
- **Three-State Outputs:** Supports bus-oriented applications.  

This device is primarily used in high-speed computing and communication systems where fast parity generation/checking is required.

Application Scenarios & Design Considerations

Look-Ahead Carry Block

Alternative Part Number

  • SN74F257N --: Quad 2-to-1 multiplexer in DIP-16, functionally similar to the MC10H179 quad multiplexer and widely available.
  • MC74F257AN --: Quad 2-to-1 multiplexer with TTL-compatible inputs, a practical substitute for the ECL-based MC10H179 in many designs.
  • 74F257PC --: Standard 74F257 quad multiplexer in PDIP, offering similar logic function and pin-compatible DIP footprint.
  • MC10H179FN --: Same MC10H179 function from the successor of Motorola, in a PLCC package; electrically equivalent and widely available.
  • MC10H179P --: Same MC10H179 device in a DIP package, drop-in functional replacement when package footprint allows.
  • SY10H179L --: Second-source ECL/PECL device with equivalent function and pinout, usable as a direct alternative.
  • SN74F74N --: Dual D-type flip-flop in a DIP package, functionally similar to the MC10H179L and widely available as a general-purpose logic replacement.
  • MC74F74N --: Dual D flip-flop with compatible logic function and DIP pinout, from a different series than the original MECL part.
  • 74F74PC --: Standard 74F dual D-type flip-flop in DIP, offering a practical drop-in style alternative for the original logic function.
