General-purpose, dual-channel, 1/1 reverse pinout digital isolator

The ISO672xB devices are

high-performance, dual-channel digital isolators ideal for cost

sensitive applications requiring up to 3000 VRMS (D

package)

isolation

ratings per UL 1577. These devices are also certified by VDE, TUV,

CSA, and CQC.

The ISO672xB

devices provide

high electromagnetic immunity and low emissions at low power

consumption, while isolating CMOS or LVCMOS digital I/Os. Each

isolation channel has a logic input and output buffer separated by

TI’s double capacitive silicon dioxide (SiO2) insulation

barrier. The ISO6720B device has 2

isolation channels with both channels in the same direction. The ISO6721B device has 2

isolation channels with 1 channel in each direction. In the event of

input power or signal loss, the default output is high for

devices without suffix F and low for devices with suffix F.

See Device

Functional Modes section for further details.

Used in conjunction

with isolated power supplies, these devices help prevent noise

currents on data buses, such as UART, SPI, RS-485, RS-232, and CAN

from damaging

sensitive circuitry. Through innovative chip design and layout

techniques, the electromagnetic compatibility of the ISO672xB devices has

been significantly enhanced to ease system-level ESD, EFT, surge,

and emissions compliance. The ISO672xB family of devices is available in a

8-pin SOIC narrow-body (D) package and is a

pin-to-pin upgrade to the older generations. For

reinforced isolation requirements, refer to the ISO672x-Q1.
