9 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.

9.1 Application Information

The ISO676x devices are high-performance, six-channel digital isolators. The ISO676x devices use single-

ended CMOS-logic switching technology. The supply voltage range is from 1.71 V to 5.5 V for both supplies,

VCC1 and VCC2. Since an isolation barrier separates the two sides, each side can be sourced independently with

any voltage within recommended operating conditions. As an example, it is possible to supply ISO676x VCC1

with 3.3 V (which is within 1.71 V to 5.5 V) and VCC2 with 5V (which is also within 1.71 V to 5.5 V). You can

use the digital isolator as a logic-level translator in addition to providing isolation. 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, MCU or FPGA), and a data converter or a line

transceiver, regardless of the interface type or standard.
