Description and Introduction

CMOS Octal Latching Bus Driver The IS82C82 is a high-speed CMOS octal bus transceiver manufactured by Intersil (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Technology:** High-Speed CMOS  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Logic Family:** 82C (CMOS)  
- **Package Type:** 20-pin DIP, SOIC, or PLCC  
- **Data Rate:** High-speed operation (specific speed depends on conditions)  
- **I/O Type:** 3-state outputs  

### **Descriptions:**  
- The IS82C82 is an octal bidirectional bus transceiver designed for asynchronous communication between data buses.  
- It allows data transmission in both directions (A to B or B to A) based on the direction control input.  
- The output enable (OE) pin controls the outputs, allowing them to be placed in a high-impedance state.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by direction (DIR) pin.  
- **3-State Outputs:** Allows bus isolation when outputs are disabled.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Typical of CMOS logic.  
- **Wide Operating Voltage Range:** Compatible with 5V systems.  
- **ESD Protection:** Helps prevent damage from electrostatic discharge.

Application Scenarios & Design Considerations

CMOS Octal Latching Bus Driver

Alternative Part Number

  • CD82C82 --: Harris second-source CMOS octal latch in the same 82C82 family with equivalent pinout and function, widely available as a direct replacement.
  • SN74HC244 --: Octal buffer/line driver with 3-state outputs that can serve similar bus-driving roles in many designs, though pinout and logic family differ so verify compatibility.
  • MC74HC245A --: Octal bidirectional bus transceiver commonly used as a functional substitute for bus interface latches; requires checking pinout and timing against the original.
  • ID82C82 --: Intersil 82C82 octal bus transceiver, functionally equivalent CMOS device suitable as a drop-in substitute.
  • SN74ACT245 --: Octal bus transceiver with similar bidirectional drive capability; requires pinout verification but is a widely available functional alternative.
