MAX14930–MAX14932,
MAX14130–MAX14131
4-Channel, 1kVRMS, 2.75kVRMS
and 3.75kVRMS Digital Isolators
General Description
The MAX14930–MAX14932 are a family of 4-channel,
2.75kVRMS and 3.75kVRMS digital isolators utilizing
Maxim’s proprietary process technology. The MAX14130–
MAX14131 are 4-channel 1kVRMS digital isolators in
smaller footprint QSOP packages. For applications
requiring 5kVRMS of isolation, see the MAX14934–
MAX14936. The MAX14930–MAX14932 family transfers
digital signals between circuits with different power
domains at ambient temperatures up to +125°C.
The MAX14930–MAX14932 family offers all three possible
unidirectional channel configurations to accommodate
any 4-channel design; including SPI, RS-232, RS-485,
and digital I/O applications. For applications requiring
bidirectional channels, such as I2C, see the MAX14933.
Devices are available with data rates from DC up to
1Mbps, 25Mbps, or 150Mbps. Each device is also avail-
able 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 and 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 MAX14930–MAX14932 are available in both a 16-pin
wide body (10.3mm x 7.5mm) and narrow body (9.9mm x
3.9mm) SOIC package. The MAX14130–MAX14131 are
available in a 16-pin (6mm x 5mm) QSOP package. All
devices are rated for operation at ambient temperatures
of -40°C to +125°C.
Ordering Information and Selector Guide appears at end of
data sheet.
