The ISO774x-Q1
automotive devices
are high-performance, quad-channel
digital isolators with 5700VRMS (DWW package),
5000VRMS
(DW
package) and 3000VRMS (DBQ
package) isolation ratings per UL 1577. This
family of devices has
reinforced insulation ratings according to VDE, CSA, TUV and
CQC.
The ISO774x-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 (SiO2) insulation barrier. These devices come with enable pins which can be used to put
the respective outputs in high impedance for
multi-controller driving applications and to reduce power
consumption. The ISO7740-Q1
device has all four channels in the same
direction, the
ISO7741-Q1
device has three forward and one reverse-direction
channels, and the
ISO7742-Q1
device has two forward and two reverse-direction
channels. If the input power or signal is
lost, 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.
