LTC4304CMS#TRPBF

Signal Buffers, Repeaters, Splitters Overview

The LTC4304CMS#TRPBF is a hot swappable 2-wire bus buffer designed for I/O card insertion into live backplanes without data corruption. It provides bidirectional buffering for SDA and SCL lines, isolating backplane and card capacitances. The device features automatic stuck bus recovery by generating up to 16 clock pulses if the bus remains low for ≥30ms. It supports I²C, Fast-Mode, and SMBus standards with operation up to 400kHz. Key electrical parameters include a supply voltage range of 2.7V to 5.5V, a precharge voltage of 1V on all SDA/SCL lines, and ±15kV Human Body Model ESD protection. The component is housed in a 10-lead MSOP package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the CMS designation corresponds to the commercial temperature grade (0°C to 70°C) required for your application environment. Ensure the ordering information matches the manufacturer's current datasheet specifications to avoid discrepancies in package type or operating range.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the LTC4304CMS#TRPBF for applications requiring hot swapping capabilities on 2-wire buses. This variant is suitable for commercial temperature ranges. Consider the MSOP package size for space-constrained designs. Evaluate the need for rise-time accelerators based on total bus capacitance and pull-up resistor values to ensure compliance with I²C timing requirements.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the LTC4304 series of hot swappable bus buffers. It shares functional similarities with parts like the LTC4300A and LTC4301 but offers specific stuck bus recovery features. The CMS#TRPBF designation identifies the commercial grade version in a tape and reel format, distinguishing it from industrial grades or tube-packaged variants within the same family.
