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 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 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

All devices are 100% production tested at TA = +125°C. Specifications over temperature are guaranteed by design.
Not production tested. Guaranteed by design.
All currents into the device are positive. All currents out of the device are negative.
CMTI is the maximum sustainable common-mode voltage slew rate while maintaining the correct output. CMTI applies to both rising
and falling common-mode voltage edges. Tested with the transient generator connected between GNDA and GNDB
(VCM = 1000V).

MAX14930–MAX14932,
MAX14130–MAX14131
Detailed Description
The
MAX14930–MAX14932
and
MAX14130–
MAX14131 are a family of 4-channel digital isolators.
The MAX14930–MAX14932 family transfers digital
signals between circuits with different power domains.
The devices are rated for up to 3.75kVRMS isolation
voltage for 60 seconds. The MAX14130–MAX14131
are rated for up to 1kVRMS isolation voltage for 60
seconds. This family of digital isolators offers lowpower operation, high electromagnetic interference (EMI)
immunity, and stable temperature performance through
Maxim’s proprietary process technology. The devices
isolate different ground domains and block high-voltage/
high-current transients from sensitive or human interface
circuitry.
The devices offer three unidirectional channel configurations
for design convenience. The MAX14x30 features four
channels transferring digital signals in one direction for
applications such as isolated digital I/O. The MAX14x31
has three channels transmitting data in one direction and
one channel transmitting in the opposite direction, making
it ideal for applications such as isolated SPI and RS-485
communication. The MAX14932 provides further design
flexibility with two channels in each direction for isolated
RS-232 or other applications.
Devices are available with data rates from DC up to 1Mbps
(A/D versions), 25Mbps (B/E versions), or 150Mbps (C/F
versions). Each device can also be ordered with defaulthigh or default-low outputs. This is the state an output
will go to when the input side of the device is unpowered.
The devices have two supply inputs, VDDA and VDDB,
that independently set the logic levels on either side of
the device. VDDA and VDDB are referenced to GNDA and
GNDB, respectively. The MAX14930–MAX14932 family
also features a refresh circuit to ensure output accuracy
when an input remains in the same state indefinitely.

4-Channel, 1kVRMS, 2.75kVRMS
and 3.75kVRMS Digital Isolators
Digital Isolation
The MAX14930–MAX14932 family provides galvanic
isolation for digital signals that are transmitted between
two ground domains. Up to 630VPEAK of continuous
isolation is supported, as well as transient differences of
up o 3.75kVRMS for up to 60 seconds. The MAX14130–
MAX14131 family provides galvanic isolation for digital
signals that are transmitted between two ground domains.
Up to 424VPEAK of continuous isolation is supported, as
well as transient differences of up to 1kVRMS for up to 60
seconds.
Level Shifting
The wide supply voltage range of both VDDA and
V DDB allows the MAX14930–MAX14932 and
MAX14130–MAX14131 family to be used for level translation in addition to isolation. VDDA and VDDB can
be independently set to any voltage from 1.71V to
5.5V. The supply voltage sets the logic level on the
corresponding side of the isolator.
Unidirectional Channels
Each channel of the MAX14930–MAX14932 and
MAX14130–MAX14131 is unidirectional; it only passes
data in one direction, as indicated in the functional diagram.
Each device features four unidirectional channels that
operate independently with guaranteed data rates from
DC up to 1Mbps (A/D versions), 25Mbps (B/E versions), or
150Mbps (C/F versions). The output driver of each channel
is push-pull, eliminating the need for pullup resistors. The
outputs are able to drive both TTL and CMOS logic inputs.
Startup and Undervoltage Lockout
The VDDA and VDDB supplies are both internally monitored
for undervoltage conditions. Undervoltage events can
occur during power-up, power-down, or during normal
operation due to a sagging supply voltage. When an
undervoltage condition is detected on either supply, all
outputs go to their default states regardless of the status
of the inputs (Table 1). Figure 2 through Figure 5 show the
behavior of the outputs during power-up and power-down.

Applications Information
Power-Supply Sequencing
The MAX14930–MAX14932 and MAX14130–MAX14131
do not require special power-supply sequencing. The
logic levels are set independently on either side by VDDA
and VDDB. Each supply can be present over the entire
www.maximintegrated.com
4-Channel, 1kVRMS, 2.75kVRMS
and 3.75kVRMS Digital Isolators
specified range regardless of the level or presence of the
other supply.
Power-Supply Decoupling
To reduce ripple and the chance of introducing data errors,
bypass VDDA and VDDB with 0.1µF ceramic capacitors to
GNDA and GNDB, respectively. Place the bypass capacitors
as close to the power-supply input pins as possible.
