It delivers 5000Vrms of isolation in an 8-SOIC package, supporting data rates up to 100Mbps with typical propagation delays of 16ns and rise/fall times around 1.8ns.
The device is supplied in an 8-SOIC wide-body package (7.50mm body width, 0.295" pitch). This is the standard footprint for reinforced isolation in SOIC format. The 8-pin package is surface-mount only.
The data rate is 100Mbps and the isolation voltage is 5000Vrms. These are the headline ratings for this general-purpose digital isolator.
The ISO7721FBDWR is a functional peer in the same family — same 100Mbps data rate, same 5000Vrms isolation, same 2-channel count, but with a 1/1 input/output split instead of the ISO7720's 2/0 forward-only configuration. The ISO7720 has both channels oriented in the same direction, while the ISO7721 provides one channel in each direction. Choose based on your bus direction requirements.
