3 Description
The ISO773x-Q1 devices are high-performance, triple-channel digital isolators with 5000 V RMS (DW package) and 3000 V RMS (DBQ package) isolation ratings per UL 1577.
This family includes devices with reinforced insulation ratings according to VDE, CSA, TUV and CQC.
The ISO773x-Q1 family of devices provides 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. This device comes with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption.
