Product details

The LTM2892IY-I#PBF is a µModule I²C digital isolator from Analog Devices that uses magnetic coupling to provide 3500Vrms galvanic isolation across six unidirectional channels, arranged three per side. It supports the full I²C fast-mode data rate of 400kHz and operates from a supply range of 3V to 5.5V, so it works with both 3.3V and 5V I²C buses without a level shifter. The 50kV/µs common-mode transient immunity (CMTI) makes it a strong fit for motor-drive, inverter, and industrial environments where fast voltage transients on the isolation barrier are a concern.

Six channels, unidirectional — routing the I²C bus and extra signals

With six channels split 3/3 between Side 1 and Side 2, this part handles the SDA and SCL lines in each direction plus a third signal per side — useful for an interrupt line, reset, or a dedicated enable. The unidirectional channel architecture means you assign each channel's direction at the board level; there is no bidirectional data pin like some I²C isolators use. Propagation delay is 250ns max in both directions, which keeps the bus timing within the I²C fast-mode spec for most system clock rates.

24-BGA package — footprint and handling notes

Housed in a 24-BBGA (9x6.25mm body), this is a surface-mount BGA with a 1.0mm ball pitch typical for µModule packages. The tray shipping medium means it arrives in antistatic trays, not tape-and-reel — factor that into your pick-and-place feeder setup.

Frequently asked questions

Does LTM2892IY-I#PBF support 5V logic levels on both sides?

Yes. The supply range of 3V to 5.5V on both sides means you can run Side 1 at 3.3V and Side 2 at 5V, or both at the same voltage, without external level translation. The I²C bus logic levels follow the respective supply rail.

Is LTM2892IY-I#PBF compatible with 3.3V I²C systems?

Yes. The 3V minimum supply covers 3.3V operation directly. The 400kHz data rate is within I²C fast-mode timing, and the 250ns propagation delay leaves margin for bus capacitance up to the standard 400pF limit.

Are there any drop-in replacements or equivalents for LTM2892IY-I#PBF?

There is no pin-compatible drop-in from the peer list. The ADM2484EBRWZ-REEL7 is an RS-485 transceiver with isolation, not an I²C isolator, so it serves a different bus protocol. For a functional equivalent, look for other I²C-specific digital isolators with 3500Vrms isolation and six channels — the LTM2892's µModule package and magnetic-coupling architecture are distinctive.
