The TPT774x devices are high-performance, 4- channel digital isolators with 5000 VRMS (WSOP-16 packages), 3750 VRMS (SOP-16, QSOP-16 package), isolation ratings per UL 1577. These devices are also to be certified by VDE, UL, CSA, CQC and CB. The TPT774x devices provide high reliability and high performance at low power consumption while isolating digital input and output. Each isolation signal channel is separated by a double capacitive silicon dioxide insulation barrier. The TPT7740 device has four channels in the same direction while the TPT7741 device has three channels in the forward direction and one channel in opposite direction. The TPT7742 device has two channels in the forward direction and two channels in opposite direction. In the event of input power or signal loss, the default output is low for devices with suffix F and high for devices without suffix F. The common mode transient immunity (CMTI) and electromagnetic compatibility of the TPT774x devices have been significantly enhanced through innovative circuit design and optimized structure. TPT774x family is available in SOP-16, QSOP-16, WSOP-16 package, and is characterized from −40°C to +125°C.
