What are the key features of LTC4300A-2CMS8#PBF?
- 2-channel bidirectional I2C/SMBus buffer with capacitance isolation enables hot-swap card insertion without corrupting existing bus transactions
- Supports standard and fast-mode 2-wire bus speeds up to 400 kHz while extending total bus capacitance beyond the 400 pF I2C limit
- 8-pin MSOP package with integrated bus logic minimizes external components for live-insertion backplane and mezzanine card designs
What is LTC4300A-2CMS8#PBF used for?
The LTC4300A-2CMS8#PBF is used in server backplanes, ATCA chassis, and industrial rack systems where mezzanine cards or plug-in modules must be inserted and removed while the I2C bus is active. Its 2-channel buffering isolates downstream bus capacitance, allowing the host bus to operate with many more devices than the standard 400 pF limit would permit. The hot-swap controller function prevents bus glitches during live insertion, ensuring reliable communication with all other devices on the shared 2-wire bus.

Frequently Asked Questions
How does the LTC4300A-2CMS8#PBF handle bus capacitance isolation on a crowded I2C backplane?
The LTC4300A-2CMS8#PBF uses bidirectional current-source buffers to isolate the downstream card bus from the upstream host bus, preventing the cumulative capacitance of multiple plug-in cards from exceeding the 400 pF I2C limit and allowing designs with 10 or more modules on a single host segment.
What I2C bus speeds does the LTC4300A-2CMS8#PBF support, and is it compatible with SMBus?
The LTC4300A-2CMS8#PBF supports standard-mode (100 kHz) and fast-mode (400 kHz) I2C operation and is fully compatible with SMBus, making it suitable for system management interfaces in servers, telecom equipment, and industrial controllers that use SMBus for power sequencing and status monitoring.
What happens to the I2C bus when a card is hot-inserted with the LTC4300A-2CMS8#PBF in place?
During hot insertion, the LTC4300A-2CMS8#PBF holds the downstream bus until it is stable before connecting it to the upstream host bus, preventing the new card's bus capacitance — which can be hundreds of picofarads — from causing a glitch that would reset or corrupt transactions on the other 2-channel connected devices.
