Description and Introduction

CMOS Clock Generator Driver The **IP82C84A** is a clock generator and driver IC manufactured by **Harris Semiconductor** (now part of Intersil). Below are the key specifications, descriptions, and features based on available information:  

### **Manufacturer:**  
- **Harris Semiconductor** (now part of **Intersil/Renesas**)  

### **Specifications:**  
- **Function:** Clock Generator and Driver for Microprocessors  
- **Compatibility:** Designed for Intel 8086/8088 and other compatible microprocessors  
- **Clock Output:** Provides system clock (CLK), peripheral clock (PCLK), and oscillator output (OSC)  
- **Frequency Range:** Supports crystal or external clock input (typically up to 10 MHz)  
- **Power Supply:** +5V DC  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions:**  
- The **IP82C84A** generates and conditions clock signals for microprocessor-based systems.  
- It includes an oscillator section, divide-by-3 counter, and buffered outputs for system synchronization.  
- Used in early x86-based systems to provide stable clock signals for the CPU and peripherals.  

### **Features:**  
- **Crystal Oscillator Input:** Supports external crystal or TTL-level clock input.  
- **Buffered Outputs:** Provides clean, stable clock signals (CLK, PCLK, OSC).  
- **Reset Synchronization:** Includes a reset input for system initialization.  
- **Low Power Consumption:** CMOS technology for efficient operation.  
- **DIP Package:** Typically available in a **20-pin DIP** (Dual In-line Package).  

This information is based on historical datasheets and technical documentation. For exact specifications, refer to the official datasheet from the manufacturer.

Application Scenarios & Design Considerations

CMOS Clock Generator Driver

Alternative Part Number

  • 82C84A --: Same clock generator function and pinout from the same manufacturer, differing only by the package/ordering prefix, making it a direct drop-in replacement.
  • CD82C84A --: Harris second-source equivalent of the 82C84A clock generator with identical functionality and timing, widely used as a substitute.
  • ICM82C84A --: Pin-compatible CMOS clock generator equivalent to the 82C84A, suitable for direct replacement in most designs.
