MAX14936. The MAX14930–MAX14932 family transfers
digital signals between circuits with different power
domains at ambient temperatures up to +125°C.
● Interfaces Directly with Most Micros and FPGAs
• Accepts 1.71V to 5.5V Supplies
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
● Many Options Support Broad Applications
• 3 Data Rates (1Mbps, 25Mbps, 150Mbps)
• 3 Channel Direction Configuration
• 2 Output Default States (High or Low)
• 3 Packages (3.8mm, 4mm, 8mm Creepage and
Clearance)

bidirectional channels, such as I C, 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 Product Selector Guide and Ordering
Information 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.
