MAX12931BASA+

The MAX12930/MAX12931 are a family of 2-channel,
3kV/5kVRMS digital galvanic isolators using Maxim’s
proprietary process technology. These devices transfer
digital signals between circuits with different power domains
while using as little as 0.65mW per channel at 2Mbps with 1.8V.
The two channels of the MAX12931 transfer data in
opposite directions, and this makes the MAX12931 ideal
for isolating the TX and RX lines of a transceiver. The
MAX12930 features two channels transferring data in the
same direction.
Both devices are available with a maximum data rate
of either 25Mbps or 150Mbps and with the default
outputs that are either high or low. The default is
the state the output assumes when the input is not
powered, or if the input is open-circuit. See the
Ordering Information and Product Selector Guide for
suffixes associated with each option. Independent 1.71V
to 5.5V supplies on each side of the isolator also make
the devices suitable for use as level translators.
The MAX12930/MAX12931 are available in an 8-pin,
narrow-body SOIC package. In addition, the MAX12931
is available in a 16-pin, wide-body SOIC package. The
package material of the 8-pin narrow-body SOIC package
has a minimum comparative tracking index (CTI) of 400,
which gives it a group II rating in creepage tables. The
package material of the 16-pin wide-body SOIC package
has a CTI of 600, which gives it a group I rating in creepage tables. All devices are rated for operation at ambient
temperatures of -40°C to +125°C.
