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 ISO773x devices are high-performance, triple-channel digital isolators. These devices come with enable
pins on each side which can be used to put the respective outputs in high impedance for multi-controller driving
applications and reduce power consumption. The ISO773x family of devices use single-ended CMOS-logic
switching technology. The 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 ISO7731 device, combined with Texas Instruments' mixed-signal microcontroller, RS-485 transceiver,
transformer driver, and voltage regulator, can create an isolated RS-485 system as shown in Figure 8-1.
