3 Description
The ISO604x devices are high performance digital
isolators designed for applications requiring up to
5000VRMS isolation rating per UL 1577. The devices
are also certified by VDE, TUV, CSA, and CQC. See
Section 6.7 for details.
The ISO604x devices provide high data rates at very
low supply current with low propagation delay, low
jitter and low channel to channel and part to part skew
while isolating CMOS or LVCMOS digital I/Os. These
devices come with enable pins that can be used to put
the respective outputs in high impedance.
Devices in the family have channel configurations for
specific numbers of forward and reverse directions
across the isolation barrier, default output levels,
and packaging. See the Device Comparison section
for details on the device configurations. Four
channel device configurations accommodate any four
channel design, including SPI, RS-485, and digital
I/O applications. Multiple four channel devices or
combinations with two and six channel devices can
be used to transmit any number of parallel I/O, SPI
chip selects, status or fault signals required by the
application.
