ISO644x/ISO644x-Q1 Quad-Channel Digital Isolators

Texas Instruments ISO644x/ISO644x-Q1 Quad-Channel Digital Isolators are general-purpose digital isolators designed for applications requiring up to a 5000V_RMS isolation rating per UL 1577. The devices are also certified by VDE, TUV, CSA, and CQC. The ISO644x devices provide high EMC performance while isolating CMOS or LVCMOS digital I/Os. ISO644x/ISO644x-Q1 uses SiO₂ as the isolation barrier. Each isolation channel has an output buffer and logic input separated by the insulation barrier. These devices come with enable pins that can be used to put the respective outputs in high impedance. The ISO644x-Q1 devices are AEC-Q100 qualified for automotive applications.
