General Description  
Benefits and Features  
● Robust Galvanic Isolation of Digital Signals  
• Withstands up to 2.75kV for 60s (V  
The MAX14930–MAX14932 are a family of 4-chan-  
nel 2.75kV digital isolators utilizing Maxim’s  
proprietary process technology. The MAX14130–  
MAX14131 are 4-channel 1kV digital isolators in

• Withstands ±10kV Surge per IEC 61000-4-5  
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 (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.  
Safety Regulatory Approvals  
(see Safety Regulatory Approvals)  
● UL According to UL1577  
● cUL According to CSA Bulletin 5A  
● VDE 0884-11 Basic Insulation  
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.  
Applications  
● Fieldbus Communications for Industrial Automation  
● Isolated SPI, RS-232, RS-485/RS-422  
● General Multichannel Isolation Applications  
● Battery Management
