3 Description

The ISO772x-Q1 devices are high-performance, dual-

channel digital isolators with 5000 V

RMS

(DW and

DWV packages) and 3000 V

RMS

(D package) isolation

ratings per UL 1577. This family includes devices with

reinforced insulation ratings according to VDE, CSA,

TUV and CQC.

The ISO772x-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 a double

capacitive silicon dioxide (SiO

2

) insulation barrier.

The ISO7720-Q1 device has both channels in the

same direction while the ISO7721-Q1 device has both

channels in the opposite 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 the 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 CAN and LIN, from damaging

sensitive circuitry. Through innovative chip design and

layout techniques, the electromagnetic compatibility

of the ISO772x-Q1 devices has been significantly

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

and emissions compliance. The ISO772x-Q1 family

of devices is available in 16-pin SOIC wide-body

(DW), 8-pin SOIC wide-body (DWV), and 8-pin SOIC

narrow-body (D) packages.
