MAX14934–MAX14936
Four-Channel, 5kV
RMS
Digital Isolators
The MAX14934–MAX14936 are a family of four-channel,
5kV
RMS
digital isolators utilizing Maxim’s proprietary
process technology. For applications requiring 2.75kV
RMS
of isolation, see the MAX14930–MAX14932. The
MAX14934–MAX14936 family transfers digital signals
between circuits with different power domains at ambient
temperatures up to +125°C.
The MAX14934–MAX14936 family offers all three pos-
sible unidirectional channel configurations to accom-
modate any four-channel design, including SPI, RS-232,
RS-485, and large digital IO modules. For applications
requiring bidirectional channels, such as I
2
C, refer to the
MAX14937.
Devices are available with data rates from DC up to
1Mbps, 25Mbps, or 150Mbps. Each device is also available
in either a default high or default low configuration. The
default is the state an output goes to when its input is
unpowered. See the
Ordering Information/Selector Guide
for the 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 MAX14934–MAX14936 are available in a 16-pin
wide body (10.3mm x 7.5mm) SOIC package. All devices
are rated for operation at ambient temperatures of -40°C
to +125°C.
Ordering Information/Selector Guide
appears at end of data
sheet.
