TPT772x-S
2-Channel Enhanced High-Performance Digital Isolator
Features
Description
The TPT772x devices are high-performance, dual-channel
enhanced digital isolators with 5000-VRMS (WSOP8,
WSOP16), and 3750-VRMS (SOP8) isolation ratings per UL
1577. These devices have also been certified by VDE, UL,
CSA, TUV, CQC, and CB.

The TPT772x 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 TPT7720 device has both channels in the
same direction while the TPT7721 devices have both
channels in the opposite direction. In the event of input
power or signal loss, the fail-safe default output is low for
devices with the suffix F and high for devices without the
suffix F.
