LTC4313IMS8-2#TRPBF

Signal Buffers, Repeaters, Splitters Overview

The LTC4313IMS8-2#TRPBF is a hot swappable 2-wire bus buffer with high noise margin, operating within an ambient temperature range of -40°C to +85°C. It supports bidirectional buffering for I2C and SMBus protocols at frequencies up to 400 kHz. The device operates on a supply voltage (VCC) between 2.9 V and 5.5 V, with a typical input supply current of 8.1 mA when enabled. It features a 2.5 mA rise time accelerator current source for SDA and SCL lines. The component is housed in an 8-lead MSOP package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides bidirectional buffering for 2-wire buses while maintaining a high noise margin up to 0.3 times VCC.
• Includes a 2.5 mA rise time accelerator current source to reduce bus rise times in heavily loaded systems.
• Supports level translation between 3.3V and 5V busses and prevents data corruption during live board insertion.
• Features automatic stuck bus disconnect and recovery by generating clock pulses to free stuck low conditions.

Signal Buffers, Repeaters, Splitters Applications

• Bidirectional buffering to increase fanout on I2C and SMBus networks
• Live board insertion and removal from backplanes in telecommunications systems
• Level translation between 3.3V and 5V bus segments
• Capacitance buffering for bus extenders in ATCA systems

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging configuration. Confirm that the IMS8 designation corresponds to the 8-lead plastic MSOP package type. Ensure the 'I' grade matches the required industrial temperature range specifications for the target application environment.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this variant over the LTC4313-1 if a fixed 2.5 mA pull-up current is preferred over the slew-limited switch mode. Choose the IMS8 package for surface mount assembly requirements. Verify compatibility with non-compliant I2C devices driving high VOL levels due to the high noise margin architecture.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the LTC4313 family of 2-wire bus buffers manufactured by Analog Devices. It shares functional similarities with the LTC4313-1 and LTC4313-3 but differs in its rise time accelerator implementation and supported voltage levels. The IMS8 suffix specifically denotes the MSOP package format.
