The TCA4311ADR from Texas Instruments is a 2-bit bidirectional buffer designed for hot-swappable I2C and SMBus applications. It operates within a wide power-supply voltage range of 2.7V to 5.5V, making it versatile for various system designs.
This buffer enhances I2C bus performance by increasing fanout and preventing corruption during live board insertion or removal due to its 1-V precharge on SDA and SCL lines. The input and output lines are isolated, accommodating both Standard Mode and Fast Mode I2C devices while improving noise immunity.
Packaged in an 8-SOIC format, the TCA4311ADR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. Key features include an enable pin and a READY open-drain output that supports clock stretching, arbitration, and synchronization.
Applications for the TCA4311ADR include hot board insertion and bus extension, where reliable communication over the I2C bus is critical.
