3 Description

The ISO652x-Q1 devices are high-performance,

dual-channel functional isolators designed for cost

sensitive, space constrained applications that require

isolation for non-safety applications. The isolation

barrier supports a working voltage of 450VRMS and

transient over voltages of 1000VDC.

The ISO652x-Q1 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.

ISO6520-Q1 has two isolation channels with both

channels in the same direction. ISO6521-Q1 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.

These devices help prevent ground loops and noise

currents between mixed voltage domain systems

on data buses, such as CAN and LIN, from

causing data corruption. Through chip design and

layout techniques, the electromagnetic compatibility

of the ISO652x-Q1 devices have been significantly

enhanced to ease system-level ESD and emissions

compliance.
