Description and Introduction

CMOS Octal Inverting Bus Transceiver The IP82C87H is a high-performance CMOS numeric data processor (NDP) manufactured by Harris Semiconductor. Below are its key specifications, descriptions, and features:

### **Specifications:**
1. **Manufacturer:** Harris Semiconductor  
2. **Part Number:** IP82C87H  
3. **Technology:** CMOS  
4. **Package:** 40-pin CERDIP (Ceramic Dual In-Line Package)  
5. **Operating Voltage:** 5V  
6. **Clock Speed:** Up to 8 MHz  
7. **Compatibility:** Fully compatible with Intel 80C86/80C88 and 80C286 microprocessors  
8. **Data Bus Width:** 16-bit  
9. **Instruction Set:** IEEE 754 compliant floating-point arithmetic  

### **Descriptions:**
- The IP82C87H is a high-speed numeric coprocessor designed to enhance the mathematical processing capabilities of microprocessors.  
- It accelerates floating-point arithmetic, trigonometric, logarithmic, and exponential calculations.  
- It operates in parallel with the host CPU, offloading complex mathematical operations to improve system performance.  

### **Features:**
1. **High-Speed Processing:** Executes floating-point operations significantly faster than software emulation.  
2. **IEEE 754 Compliance:** Supports single, double, and extended precision floating-point formats.  
3. **Wide Compatibility:** Works seamlessly with Harris and Intel microprocessors.  
4. **Low Power Consumption:** CMOS technology ensures efficient power usage.  
5. **Error Detection:** Includes internal error detection for invalid operations, overflow, and underflow.  
6. **Versatile Instruction Set:** Supports arithmetic, transcendental, and data transfer operations.  
7. **Temperature Range:** Operates reliably in industrial temperature ranges.  

This information is based solely on the factual specifications provided in Ic-phoenix technical data files for the IP82C87H by Harris Semiconductor.
