Description and Introduction

CMOS Clock Generator Driver The **IP82C84A** is a clock generator and driver IC manufactured by **Intersil**. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Intersil  
- **Type:** Clock Generator & Driver  
- **Package:** 18-pin DIP (Dual In-line Package)  
- **Operating Voltage:** 5V  
- **Frequency Range:** Up to 10 MHz  
- **Output Type:** TTL-compatible  
- **Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Description:**  
The **IP82C84A** is a CMOS clock generator and driver designed for use with microprocessors, particularly the Intel 8086/8088 family. It provides essential clock signals, including the system clock (CLK), ready synchronization (READY), and reset synchronization (RESET).  

### **Features:**  
- Generates **CLK**, **READY**, and **RESET** signals for microprocessor systems.  
- **TTL-compatible** outputs for direct interfacing with logic circuits.  
- **Crystal oscillator** or external clock input option.  
- **Power-on reset** functionality.  
- **Low power consumption** (CMOS technology).  
- **High noise immunity** for reliable operation.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

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.
