LTC4313CMS8-1#TRPBF

Signal Buffers, Repeaters, Splitters Overview

The LTC4313CMS8-1#TRPBF is a hot swappable 2-wire bus buffer manufactured by Analog Devices Inc. It provides bidirectional buffering for I2C and SMBus interfaces while maintaining a high noise margin up to 0.3 times VCC. The device supports level translation between 3.3V and 5V busses. Key electrical parameters include a supply voltage range of 2.9V to 5.5V, a maximum clock frequency of 400kHz, and an input capacitance of 10pF. It features rise time accelerators with a typical pull-up current of 25mA. The component operates within a temperature range of 0°C to 70°C and is housed in an 8-lead MSOP package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the CMS8 designation corresponds to the commercial temperature grade and MSOP package type required for your design. Ensure compatibility with the manufacturer's lead-free finish standards before finalizing procurement orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the LTC4313CMS8-1 variant specifically for applications requiring operation between 3.3V and 5V busses. This model includes rise time accelerators suitable for heavily loaded buses where standard pull-up resistors may fail to meet timing requirements. Consider the commercial temperature range limits when designing for industrial or automotive environments.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the LTC4313 family of 2-wire bus buffers designed for hot swap applications. The -1 suffix distinguishes it from other variants by supporting specific voltage levels and including rise time accelerator functionality. It serves as a critical interface element for isolating backplane capacitance from sensitive peripheral devices.
