Description

The LTC4311ISC6#TRPBF is a digital bus isolator specifically designed for I²C and SMBus applications. It enables bidirectional communication across isolation barriers, facilitating the connection of devices operating at different voltage levels. The chip supports hot-swapping, allowing it to be integrated into live circuits without disrupting operations.
Key features include:
- Operating voltage range: 1.8V to 5.5V
- High-speed data rates up to 1 MHz
- Integrated pull-up resistors for simplified design
- Robust protection against electrical noise and transients
The device is housed in a compact 6-lead SC-70 package, making it suitable for space-constrained applications. Its isolation capability is ideal for applications requiring separation between system components for safety or performance reasons, such as in industrial controls, medical devices, and automotive systems.
Overall, the LTC4311 is a versatile solution for enhancing communication integrity in multi-voltage I²C networks.

Features

The LTC4311ISC6#TRPBF is a high-speed I²C bus buffer designed to extend the reach and improve the signal integrity of I²C communications. Key features include:
1. Bus Buffering: It buffers both the SDA and SCL lines, allowing for longer cable lengths and increased capacitance.
2. High Speed: Supports data rates up to 1 MHz, suitable for fast I²C applications.
3. Active Pull-Up: Integrated active pull-up transistors enhance rise times, reducing delays on the bus.
4. Wide Operating Voltage: Operates in a voltage range of 1.8V to 5.5V, making it compatible with various I²C devices.
5. Low Power Consumption: Features low quiescent current, ideal for battery-powered applications.
6. Multiple Device Support: Can connect multiple devices on the I²C bus without significant signal distortion.
7. Thermal Shutdown: Includes built-in thermal protection to prevent overheating.
These features make the LTC4311ISC6#TRPBF suitable for applications requiring reliable communication in complex I²C networks.

Package

The LTC4311ISC6#TRPBF is packaged in a 6-lead SC-70 (SOT-23) surface mount package. This compact package is designed for space-constrained applications, providing efficient thermal performance and ease of integration into circuits.

Pinout

The LTC4311ISC6#TRPBF is an I2C bus isolator with a pin count of 6. It is designed to provide isolation and improve system reliability in I2C communications. The key functions of its pins are:
1. VCC - Power supply for the device.
2. GND - Ground connection.
3. SDA - Serial Data Line for I2C communication.
4. SCL - Serial Clock Line for I2C communication.
5. SEL - Select pin to configure the device for different isolation modes (e.g., 1.5kΩ pull-up or 10kΩ pull-up for SDA/SCL).
6. ISO - Isolation pin that enables or disables the I2C signal isolation feature.
This device helps maintain signal integrity over longer distances and in harsh environments by isolating the I2C bus while allowing data transfer between master and slave devices.
