概要

Description

The P82B96DR is a dual-channel, bidirectional I2C bus controller designed for interfacing microcontrollers with I2C peripherals. It is particularly useful in applications requiring communication with multiple devices on the same bus. The P82B96DR enhances the standard I2C bus by enabling longer distances and higher capacitance loads through the use of bus buffer technology.
Key features include support for standard and fast-mode I2C communications, a wide voltage operation range, and the ability to drive the bus lines over extended lengths. The device is typically used in applications such as industrial automation, sensor networks, and other embedded systems where multiple devices need to communicate efficiently.
The P82B96DR is packaged in a compact form, making it suitable for space-constrained designs. Its robust design ensures reliable performance in various operating conditions. The device is compatible with most microcontrollers, simplifying integration into existing systems.

Features

The P82B96DR is a dual bidirectional I²C bus buffer designed for communication in I²C systems, especially useful for long-distance data transmission. Key features include:
1. Dual Channel: Supports two separate I²C buses, allowing for increased flexibility in system design.
2. Buffering: Provides isolation between the master and slave devices, reducing bus capacitance and improving signal integrity over longer distances.
3. Voltage Level Translation: Capable of operating with different voltage levels, making it suitable for interfacing devices with varying supply voltages.
4. High-Speed Operation: Supports standard (100 kHz), fast (400 kHz), and fast-mode plus (1 MHz) I²C speeds.
5. Low Power Consumption: Designed for efficiency, ensuring minimal power draw during operation.
6. Wide Operating Voltage Range: Compatible with a voltage range from 1.8V to 5.5V, enhancing versatility across applications.
The P82B96DR is ideal for applications requiring robust and reliable I²C communication in complex systems.

Package

The P82B96DR is packaged in a dual-in-line package (DIP) with a 16-pin configuration.

Pinout

The P82B96DR is an integrated circuit designed for I2C bus communication with extended distance capabilities. It has a total of 8 pins.
The functions of the pins are as follows:
1. VCC (Pin 1): Positive supply voltage.
2. GND (Pin 2): Ground connection.
3. SDA1 (Pin 3): Serial Data Line for I2C bus, side 1.
4. SCL1 (Pin 4): Serial Clock Line for I2C bus, side 1.
5. SDA2 (Pin 5): Serial Data Line for I2C bus, side 2.
6. SCL2 (Pin 6): Serial Clock Line for I2C bus, side 2.
7. VREF (Pin 7): Reference voltage for the bus.
8. NC (Pin 8): No connection (not used).
The P82B96 allows for I2C communication over longer distances by converting the signals to a more suitable format for transmission.
