It provides 2500Vrms of galvanic isolation across the barrier, rated for a 2Mbps data rate with 2ns typical rise/fall times and 25kV/µs minimum common-mode transient immunity. The 3/1 input-side/side-2 channel configuration (three inputs on side 1, one on side 2) suits designs where the majority of signals flow from one domain to the other, such as isolating a microcontroller's SPI or UART lines from a noisy power stage or sensor interface. ## What the 25kV/µs CMTI buys you The 25kV/µs common-mode transient immunity is the headline spec for anyone placing this isolator in a motor drive, inverter, or switched-mode power supply. Fast voltage transients across the isolation barrier — from IGBT switching edges or relay arcs — can couple enough charge to corrupt a data bit if the isolator's CMTI is too low. At 25kV/µs minimum, this part handles the edge rates found in most industrial drives without glitching the output. The 180ns propagation delay (max) is typical for a 2Mbps-rated coupler; budget that into your timing closure if the isolated link carries a synchronous clock or a time-critical enable signal. ## Temperature range and package fit The 16-SSOP package (3.90mm width) maps to a 16-QSOP footprint per the supplier device package — a common, low-profile land pattern that fits tight board stacks. Supply range is 2.25V to 3.6V, so it runs from a 3.3V or 2.5V rail without a separate regulator; check that both sides of the barrier stay within that window.","metaTitle":"ADUM1446ARQZ-RL7 iCoupler Digital Isolator, 2500Vrms, 2Mbps","metaDescription":"ADUM1446ARQZ-RL7 4-channel general-purpose digital isolator, 2500Vrms isolation, 2Mbps data rate, -40°C to 125°C.
