ISO164x Hot-Swappable Bidirectional I2C Isolators with Enhanced EMC and GPIOs

1 Features

3 Description

•

Reliable Isolated Bidirectional, I²C Compatible,

Communication

– ISO1640: Bidirectional Isolated SDA and SCL

communication

– ISO1641: Bidirectional SDA and unidirectional

SCL communcation

– Hot Swappable SDA and SCL

Bidirectional data transfer up to 1.7 MHz Operation

The ISO1640 and ISO1641 (ISO164x) devices are

hot swappable, low-power, bidirectional isolators that

are compatible with I²C interfaces. The ISO164x

supports UL 1577 isolation ratings of 5000 V_RMS

in the 16-DW package, and 3000 V_RMSin the 8-D

package. Each isolation channel in this low emissions

device has a logic input and open drain output

separated by a double capacitive silicon dioxide

(SiO₂) insulation barrier. This family includes basic

and reinforced insulation ratings devices certified by

VDE, UL, CSA, TUV and CQC. The ISO1640 has

two isolated bidirectional channels for clock and data

lines while the ISO1641 has a bidirectional data

and a unidirectional clock channel. The ISO164x

family integrates logic required to support bidirectional

channels, providing a much simpler design and

smaller footprint when compared to optocoupler-

based solutions.
