TPT7742

4-Channel Enhanced High-Performance Digital Isolator

Overview

The TPT774x devices are high-performance, 4-channel digital isolators with 5000-VRMS (WSOP16), and 3750-VRMS (SOP16, QSOP16) isolation ratings per UL 1577. These devices are also to be certified by VDE, UL, CSA, TUV, CQC, and CB.

The TPT774x devices provide high reliability and high performance at low power consumption with 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 the opposite direction. The TPT7742 device has two channels in the forward direction and two channels in the opposite direction. In the event of input power or signal loss, the default output is low for devices with the suffix F and high for devices without the 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.

The TPT774x family is available in SOP16, QSOP16, and WSOP16 packages, and is characterized from -40°C to +125°C.
