Product details

Quad-channel digital isolator for industrial and mixed-voltage domains

The device is housed in a 16-lead SSOP (3.90 mm width) and also specified as a 16-QSOP supplier device package, both surface-mount footprints suitable for compact PCB layouts.

Maximum propagation delay is 180 ns in both directions (tpLH and tpHL), with a pulse-width distortion of 8 ns max. Rise and fall times are typically 2 ns. These numbers matter when budgeting timing for a clocked interface: at 2 Mbps the bit period is 500 ns, so the 180 ns delay consumes about 36% of the period — enough margin for most designs, but a constraint if daisy-chaining multiple isolators in the same path.

ROHS3 compliant.

Frequently asked questions

Is ADUM1447ARQZ-RL7 obsolete or end-of-life?

No — it is listed as active (current production) with no end-of-life notice. No last-time-buy risk for new designs.

What is the data rate of ADUM1447ARQZ-RL7?

2 Mbps, which suits SPI, UART, and general-purpose digital isolation at moderate speeds.

What are equivalent parts to ADUM1447ARQZ-RL7?

Within the iCoupler family, the ADUM1445 and ADUM1446 offer different channel-direction configurations (e.g., 3/1 or 1/3 splits) but share the same package, isolation rating, and data rate. For a pin-compatible drop-in with the same 2/2 channel arrangement, the ADUM1447 is the correct variant.
