The ADuM7640/ADuM7641/ADuM7642/ADuM76431 are  
6-channel digital isolators based on the Analog Devices, Inc.,  
iCoupler® technology. These 1 kV digital isolation devices are  
packaged in a small 20-lead QSOP. They offer space savings and  
a lower price than 2.5 kV or 5 kV isolation solutions when only  
functional isolation is needed.

This family, like many Analog Devices isolators, offers very low  
power consumption, using one-tenth to one-sixth the power of  
other digital isolators, with the supply voltage on either side  
ranging from 3.0 V to 5.5 V. Despite their low power consumption,  
the ADuM7640/ADuM7641/ADuM7642/ADuM7643 provide  
low pulse width distortion (< 6 ns for C grade) and a channel-  
by-channel glitch filter to protect the device against extraneous  
noise disturbances. Four channel direction combinations are  
available with a maximum data rate of 1 Mbps or 25 Mbps. All  
products have a default output high logic state in the absence of  
input power.
