TCA4307DRGR

Hot Swap Controllers Overview

The TCA4307DRGR is a hot-swappable I2C bus buffer manufactured by Texas Instruments, designed for signal buffering and repeater applications. It features two channels with a propagation delay of 70 ns and supports a maximum clock frequency of 14 kHz. The device operates within a supply voltage range of 2.3 V to 5.5 V and functions across an extended temperature range from -40°C to +125°C. Packaged in an 8-lead SON (DRG) format, it delivers an output current of 50 mA and draws a typical operating supply current of 100 mA. With an input capacitance of 1.6 pF, this component is suitable for server environments requiring reliable interface management.

Hot Swap Controllers Feature Summary

• Supports hot-swappable operations on I2C buses without system disruption
• Provides dual-channel signal buffering for enhanced bus isolation
• Operates reliably across wide industrial temperature ranges

Hot Swap Controllers Applications

• Server systems requiring robust I2C interface management
• Hot-swappable peripheral connections in data centers
• Signal buffering in complex multi-drop I2C networks

Hot Swap Controllers Procurement Notes

Verify the specific suffix DRG confirms the 8-lead SON package and reel packaging configuration. Ensure compatibility with I2C bus standards and voltage levels between 2.3 V and 5.5 V. Confirm that the 14 kHz maximum clock frequency meets system timing requirements. Check for RoHS compliance documentation if environmental regulations apply to your deployment. Validate that the 50 mA output current capability is sufficient for your load conditions.

Hot Swap Controllers Selection Notes

Select this component when hot-swap capability is required for I2C buses to prevent bus contention during insertion. The dual-channel architecture allows for isolated buffering of multiple lines. Consider the 70 ns propagation delay for timing-sensitive applications. The wide operating voltage range accommodates various logic levels. Ensure the SON package fits within your PCB space constraints while maintaining thermal performance at high temperatures.

Hot Swap Controllers Part Context
