1-2011 2 Applications • Power supplies • Grid, Electricity meter • Motor drives • Factory automation • Building automation • Lighting • Appliances 3 Description The ISO672xB devices are high-performance, dualchannel digital isolators ideal for cost sensitive applications requiring up to 3000 VRMS (D package) isolation ratings per UL 1577.
These devices are also certified by VDE, TUV, CSA, and CQC.
The ISO672xB devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os.
Each isolation channel has a logic input and output buffer separated by TI's double capacitive silicon dioxide (SiO2) insulation barrier.
The ISO6720B device has 2 isolation channels with both channels in the same direction.
The ISO6721B device has 2 isolation channels with 1 channel in each direction.
In the event of input power or signal loss, the default output is high for device...
