Texas Instruments ISO654x/ISO654x-Q1 Quad Functional Isolators
Texas Instruments ISO654x/ISO654x-Q1 Quad-Channel Functional Isolators are for cost-sensitive, space-constrained applications that require isolation for non-safety applications. The isolation barrier supports transient overvoltages of 707VRMS/1000VDC and a working voltage of 400VRMS/566VDC. The ISO654x devices provide high EMC performance while isolating CMOS or LVCMOS digital I/Os. ISO654x uses SiO2 as the isolation barrier. Each isolation channel has a logic output and input buffer separated by the insulation barrier. These devices come with enable pins that can be used to put the respective outputs in high impedance.
