Product details

150 Mbps capacitive-coupled isolator in an 8-SOIC

The 2500 Vrms isolation rating suits it for galvanic isolation in industrial fieldbus interfaces, motor-drive feedback paths, and isolated power-supply control loops.

The 150 Mbps data rate supports high-speed serial protocols like SPI and RS-485 without adding a timing bottleneck. The 16 ns propagation delay is symmetric (tpLH = tpHL), which keeps the pulse-width distortion to 1 ns max — important for maintaining duty cycle in PWM signals feeding an IGBT or MOSFET gate driver. If your design sees fast voltage transients across the barrier — motor drives, inverters, or any half-bridge — this CMTI rating gives you margin.

The inputs are on side 1 only (2/0 channel configuration), meaning both channels drive in the same direction — this is a unidirectional part, not a transceiver.

Frequently asked questions

What is the data rate of ISO7220MDRG4?

The ISO7220MDRG4 supports a data rate of 150 Mbps.

Does ISO7220MDRG4 support bidirectional communication?

No, the ISO7220MDRG4 has unidirectional channel types; both channels drive from side 1 to side 2 only.
