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.
