8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification, and

TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining

suitability of components for their purposes. Customers should validate and test their design

implementation to confirm system functionality.

8.1 Application Information

The ISO7710 device is a high-performance, single-channel digital isolator. The device uses single-ended CMOS-

logic switching technology. The supply voltage range is from 2.25 V to 5.5 V for both supplies, VCC1 and VCC2.

When designing with digital isolators, keep in mind that because of the single-ended design structure, digital

isolators do not conform to any specific interface standard and are only intended for isolating single-ended

CMOS or TTL digital signal lines. The isolator is typically placed between the data controller (that is, μC or

UART), and a data converter or a line transceiver, regardless of the interface type or standard.

8.2 Typical Application

The ISO7710 device can be used with Texas Instruments' mixed signal microcontroller, CAN transceiver,

transformer driver, and low-dropout voltage regulator to create an Isolated CAN Interface as shown below.
