It passes a single direction of digital signals across a 3000 Vrms isolation barrier at up to 150 Mbps, with a typical rise/fall time of 2.5 ns and a maximum propagation delay of 13 ns. ## 150 Mbps and 75 kV/µs CMTI — what they buy you 150 Mbps sustains SPI clock rates up to 75 MHz (DDR) or multiple parallel GPIO lines without bottleneck. The 75 kV/µs minimum common-mode transient immunity means this isolator holds its output state through fast voltage-slope events like motor-drive PWM edges or relay contact bounce — a key spec for motor-drive and inverter applications where ground potential shifts by hundreds of volts in microseconds. ## 4/0 channel configuration — unidirectional, all same direction All four channels run from Side 1 to Side 2 (4/0 input/output mapping). No bidirectional or reverse channels. If your application needs a return path (e.g., fault feedback from the isolated side), you will need a second device or a different channel configuration like the ADUM142D1BRQZ which offers 2/2 split. ## Package and footprint notes Surface-mount only. The narrow-body SSOP/QSOP footprint is common across many iCoupler 4-channel parts, so a layout designed for the ADUM140E1BRZ will accept this part without a board spin — same pinout, same package dimensions. ## Lifecycle and compliance ROHS3 Compliant — no exemptions expiring. No isolated power on chip; the ADUM140D0BRQZ is a pure signal isolator, not a DC/DC converter. For compliance documentation beyond RoHS, the manufacturer provides the usual iCoupler qualification package; check the lot-specific certificate of conformance at order time.","metaTitle":"ADUM140D0BRQZ iCoupler Digital Isolator, 150 Mbps, 3000 Vrms","metaDescription":"ADI ADUM140D0BRQZ digital isolator: 4-ch unidirectional, 150 Mbps, 3000 Vrms isolation, 75 kV/µs CMTI, -40°C to 125°C.
