All six inputs sit on side 1, making it a pure downstream isolator for data flowing one way — think SPI bus isolation, parallel GPIO isolation, or sensor data links where the controller talks to multiple peripherals on an isolated domain. The 75 ns propagation delay (max, both edges) and 25 ns pulse-width distortion keep timing predictable for clocked interfaces up to a few MHz. ## 15 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at 15 kV/µs minimum. In a motor-drive or inverter environment, fast-switching IGBTs or SiC FETs can slam several kilovolts per microsecond across the isolation barrier. A part with lower CMTI would latch or corrupt data; this one holds the output state through the transient. The magnetic coupling technology inherently handles these edges better than optocoupler alternatives at this speed grade. Housed in a 20-pin QSOP (3.90 mm body width), the same footprint as a standard SSOP-20.","metaTitle":"ADUM7640ARQZ-RL7 iCoupler Digital Isolator, 1 Mbps","metaDescription":"ADUM7640ARQZ-RL7 from Analog Devices: 6-channel unidirectional digital isolator, 1 Mbps data rate, 1000 Vrms isolation, -40°C to 105°C.
