3 Description

The ISO652x devices are high-performance, dualchannel

functional isolators designed for cost

sensitive, space constrained applications that require

isolation for non-safety applications.

The 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 ISO6520 device has

two isolation channels with both channels in the

same direction. The ISO6521 device has two isolation

channels with one 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 chip

design and layout techniques, the electromagnetic

compatibility of the devices has been significantly

enhanced to ease system-level ESD, EFT, surge, and

emissions compliance.
