The part does not include isolated power: you still need a separate isolated DC-DC converter to power the secondary side. ## 7500Vrms — the isolation number that matters At 7500Vrms, this part sits at the high end of USB isolators. That rating means it can withstand a 7.5 kV RMS potential across the barrier for 1 minute (typical hi-pot test). For medical equipment (IEC 60601-1 2 MOPP), industrial motor drives with big common-mode swings, or any system where a ground fault could put lethal voltage on the USB port, this is the spec that keeps the controller side safe. The common-mode transient immunity is rated at 50kV/µs minimum, so it holds its isolation through fast voltage spikes from switching supplies or relay kickback. ## 12 Mbps — USB 2.0 full speed, not high speed The LTM2894CY#PBF runs at 12Mbps, which is USB 2.0 full speed. That covers HID devices (keyboards, mice), virtual COM ports, audio, and most industrial USB peripherals. It will not work for USB 2.0 high speed (480 Mbps) or USB 3.x. The propagation delay is 115ns max each way, rise/fall time 20ns typical — fast enough for full-speed handshaking but not for isochronous video streams. If your application needs high-speed USB isolation, you need a different part (like the ADuM4160, which handles 480 Mbps).","metaTitle":"LTM2894CY#PBF USB Isolator, 7500Vrms, 12Mbps, 24-BGA","metaDescription":"Analog Devices LTM2894CY#PBF USB digital isolator: 7500Vrms isolation, 12Mbps data rate, magnetic coupling, 4.4V-36V supply.

The LTM2894CY#PBF supports a 12Mbps data rate, which is USB 2.0 full speed. It handles D+ and D- bidirectional signaling at that rate. It does not support USB 2.0 high speed (480 Mbps)."},{"question":"Does LTM2894CY#PBF require an external isolated DC-DC converter?","answer":"Yes. The LTM2894CY#PBF does not include isolated power (Isolated Power: No). You must provide a separate isolated DC-DC converter to power the secondary side of the isolation barrier."},{"question":"Can I replace LTM2894CY#PBF with LTM2884 or ADuM3160?","answer":"The LTM2884 is a USB isolator with integrated isolated power, so it is not a direct pin-compatible drop-in — you would need to rework the power supply circuitry. The ADuM3160 is a different package and isolation rating (2500Vrms typical) and does not match the 7500Vrms or the 24-BGA footprint of the LTM2894CY#PBF. Neither is a pin-compatible replacement without board changes."},{"question":"How do I get current pricing and availability for LTM2894CY#PBF?","answer":"Submit an RFQ for the LTM2894CY#PBF to receive current availability and a firm price."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTM2894CYPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTM2894CYPBF when reusing this data.
