4-Channel, 1kV_RMSand 2.75kV_RMS

Digital Isolators

General Description

The MAX14930–MAX14932 are a family of 4-chan-

• 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 (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.

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
