MAX14430–MAX14432

Four-Channel, Fast, Low-Power,

and 3.75kV Digital Isolators

3kV

RMS

General Description

Beneﬁts and Features

● Robust Galvanic Isolation for Fast Digital Signals

The MAX14430/MAX14431/MAX14432 are fast, low power,

4-channel, digital galvanic isolators using Maxim’s propri-

etary process technology. These devices transfer digital

signals between circuits with different power domains

while using as little as 0.58mW per channel at 1Mbps with

a 1.8V supply. The MAX14430–MAX14432 have an iso-

RMS

The MAX14430–MAX14432 family offers all three pos-

sible unidirectional channel configurations to accom-

modate any 4-channel design, including SPI, RS-232,

RS-485, and digital I/O applications. Output enable for

the A side of the MAX14431R/S/U/V is active-low, making

them ideal for isolating a port on a shared SPI bus since

the CS signal can directly enable the MISO signal on the

isolator. All other devices in the family have the traditional

active-high enable.

● Low Power Consumption

• 1.1mW per Channel at 1Mbps with V

= 3.3V

• 3.5mW per Channel at 100Mbps with V

= 1.8V

● Options to Support a Broad Range of Applications

• 2 Data Rates (25Mbps, 200Mbps)

• 3 Channel Direction Conﬁgurations

• 2 Output Default States (High/Low)

Devices are available with a maximum data rate of either

25Mbps or 200Mbps and with outputs that are either

default-high or default-low. The default is the state the

output assumes when the input is either not powered or is

open-circuit. See the Ordering Information and Product

Selector Guide for 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.

• Two Packages (Narrow SOIC and QSOP)

Applications

● Isolated SPI Interface

● Fieldbus Communications for Industrial Automation

● Isolated RS-485/RS-422, CAN

● Battery Management

● Medical Systems

Safety Regulatory Approvals

The MAX14430–MAX14432 are available either in a

16-pin narrow-body SOIC package with 4mm of creep-

age and clearance, or in a smaller 16-pin QSOP package

with 3.8mm of creepage and clearance. The SOIC pack-

age material has a minimum comparative tracking index

(CTI) of 600V, which gives it a group 1 rating in creepage

table. The QSOP package material has a minimum CTI of

400V, which gives it a group 2 rating in creepage table. All

devices are rated for operation at ambient temperatures of

-40°C to +125°C.

● UL According to UL1577

● cUL According to CSA Bulletin 5A
