TPT7720-SO1R

3PEAK · Digital Isolators · SOP-8

TPT7720-SO1R from 3PEAK, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCCA power_in Power supply for side A (input side). Operating range 2.25 V to 5.5 V; absolute max 6 V. Requires local bypass capacitance to GNDA.
2 IN1 input Digital input for channel 1 (side A). VIH ≥ 2 V, VIL ≤ 0.8 V referenced to GNDA; drives OUT1 on side B through the isolation barrier.
3 IN2 input Digital input for channel 2 (side A). VIH ≥ 2 V, VIL ≤ 0.8 V referenced to GNDA; drives OUT2 on side B through the isolation barrier.
4 GNDA power_in Ground reference for side A (VCCA, IN1, IN2). Isolated from GNDB by the double-capacitive silicon-dioxide barrier.
5 GNDB power_in Ground reference for side B (VCCB, OUT1, OUT2). Isolated from GNDA by the double-capacitive silicon-dioxide barrier.
6 OUT2 output Digital output for channel 2 (side B). Push-pull CMOS output referenced to VCCB/GNDB; IOH up to −4 mA and IOL up to 4 mA at VCCB = 5 V.
7 OUT1 output Digital output for channel 1 (side B). Push-pull CMOS output referenced to VCCB/GNDB; IOH up to −4 mA and IOL up to 4 mA at VCCB = 5 V.
8 VCCB power_in Power supply for side B (output side). Operating range 2.25 V to 5.5 V; absolute max 6 V. Requires local bypass capacitance to GNDB.
