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 I C, see the MAX14933.
3 Packages (3.8mm, 4mm, 8mm Creepage and Clearance)
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.

Low Power Consumption at High Data Rates
At 1.8V:
•
•
2.5mA per Channel Typical at 1Mbps
5.25mA per Channel Typical at 100Mbps
At 3.3V:
•
•
2.6mA per Channel Typical at 1Mbps
7.1mA per Channel Typical at 100Mbps
Independent 1.71V to 5.5V supplies on each side of the
isolator also make the devices suitable for use as level
translators.
Safety Regulatory Approvals
(see Safety Regulatory Approvals)
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.
