SLLSEP0A – JULY 2015 – REVISED MARCH 2016 ISO7820x High-Performance, 8000 VPK Reinforced Dual Channel Digital Isolator
1 Features 3 Description The ISO7820 is a high-performance, dual-channel
digital isolator with 8000 VPK isolation voltage. This
device has reinforced isolation certifications
according to VDE, CSA, CQC, and TUV. The isolator
provides high electromagnetic immunity and low
emissions at low power consumption, while isolating
CMOS or LVCMOS digital I/O’s. Each isolation
channel has a logic input and output buffer separated
by silicon dioxide (SiO2) insulation barrier. ISO7820
has two forward channels and no reverse-direction
channel. If the input power or signal is lost, default
output is 'high' for the ISO7820 and 'low' for the
ISO7820F device. Used in conjunction with isolated
power supplies, this device prevents noise currents
on a data bus or other circuits from entering the local
ground and interfering with or damaging sensitive …
