7 mA per channel maximum at 0 Mbps to 1 Mbps 8.
2 mA per channel maximum at 25 Mbps Bidirectional communication Up to 25 Mbps data rate (NRZ) 3 V/5 V level translation High temperature operation: 105°C High common-mode transient immunity: >15 kV/μs APPLICATIONS General-purpose multichannel isolation Data converter isolation Industrial field bus isolation GENERAL DESCRIPTION The ADuM7240/ADuM72411 are dual channel digital isolators based on the Analog Devices, Inc.
, iCoupler® technology.
Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices and other integrated couplers.
The ADuM7240/ADuM7241 dual 1 kV digital isolation devices are packaged in a narrow-body 8-lead SOIC.
The ADuM7240/ ADuM7241 offer a cost-effective option compared to 2.
5 kV or 5 kV isolators where only functional isolation is needed.
Like other Analog Devices isolators, the ADuM7240/ADuM7241 offer very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at data rates up to 25 Mbps.
Despite the low power consumption, all models of the 10240-001 FUNCTIONAL BLOCK DIAGRAMS VDD1 1 VIA 2 VIB 3 GND1 4 ENCODE ENCODE ADuM7240 DECODE DECODE Figure 1.

ADuM7241 8 VDD2 7 VIA 6 VOB 5 GND2 10240-002 ADuM7240/ADuM7241 provide low pulse width distortion (<5 ns for C grade).
In addition, every model has an input glitch filter to protect against extraneous noise disturbances.
