NCA9511-DMSR

Signal Buffers, Repeaters, Splitters Overview

The NCA9511-DMSR is a hot-swappable I2C bus buffer manufactured by NOVOSENSE, designed for signal integrity in high-speed digital interfaces. It features a single channel with a maximum data rate of 400kHz and operates within a supply voltage range of 2.7V to 5.5V. The device draws a typical operating current of 4.5mA and supports an extended industrial temperature range from -40°C to +105°C. Packaged in an 8-MSOP format measuring 3.10mm x 3.10mm with a height of 1.10mm, it includes ESD protection and is suitable for applications requiring robust bus isolation and signal buffering.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against official NOVOSENSE documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the 8-MSOP package dimensions align with your PCB footprint requirements. Check moisture sensitivity level (MSL 3) handling procedures prior to assembly to prevent soldering defects. Ensure compatibility with your target I2C clock frequencies before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing circuits requiring isolated I2C buffers with hot-swap capabilities. It is appropriate for systems needing to separate noisy power domains from sensitive logic buses. Consider its 400kHz speed limit when evaluating higher-frequency protocols like Fast Mode Plus. Verify that the 2.7V minimum supply voltage matches your system's lowest operating condition.
