This makes it a direct fit for isolating a microcontroller's SPI bus, UART, or general-purpose GPIO lines where the data direction is fixed and all signals flow one way across the barrier. ## 25 Mbps data rate and 50 ns propagation delay — timing budget for the bus With a maximum propagation delay of 50 ns in both directions and a pulse-width distortion of 6 ns, this part handles 25 Mbps signalling cleanly. The 2 ns typical rise/fall time keeps the signal edges sharp enough for a 20-pin QSOP layout, but the 15 kV/µs common-mode transient immunity ensures the barrier does not glitch when a motor drive or inverter switches at high dV/dt. No separate VDDIO or level-shifting needed if both sides run at the same voltage. If you need to cross a 3.3 V to 5 V boundary, this part does not do that — all channels are unidirectional and the supply is common to both sides. For bidirectional isolation or mixed-voltage domains, look at the ADUM7643 variant with 3/3 channel split. Housed in a 20-lead QSOP (3.90 mm body width), the same footprint as a standard SSOP-20. No AEC-Q automotive grade is listed, so for under-hood or cabin applications, check the automotive-rated iCoupler variants separately.","metaTitle":"ADUM7640CRQZ-RL7 Digital Isolator, 6-Ch, 25Mbps, 1000Vrms","metaDescription":"ADI ADUM7640CRQZ-RL7 iCoupler 6-channel digital isolator, 25 Mbps data rate, 1000 Vrms isolation, 15 kV/µs CMTI, -40°C to 105°C.

The only difference is packaging: the -RL7 suffix denotes Tape & Reel, while the base part number ships in a tube.
