TPT29617A-VS1R

3PEAK · Translators, Level Shifters · MSOP-8

TPT29617A-VS1R from 3PEAK, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VREF1 power_in Side-1 supply voltage of 0.8 V to 5.5 V that sets the port-1 comparator reference (0.35×VREF1), and the internal comparator requires 0.4×VREF1 ≤ VREF2 − 0.8 V for operation.
2 SCL1 bidirectional I2C SCL line on side 1, which must be connected to VREF1 through a pull-up resistor and is 5.5 V tolerant.
3 SDA1 bidirectional I2C SDA line on side 1, which must be connected to VREF1 through a pull-up resistor and is 5.5 V tolerant.
4 GND power_in Supply ground (0 V reference).
5 EN input Active-high repeater enable with thresholds referenced to VREF2 and an internal pull-up to VREF2; driving it low disconnects the SCL/SDA channels (high-impedance between ports), and it is 5 V tolerant and should only change state while the bus is idle.
6 SDA2 bidirectional I2C SDA line on side 2, which must be connected to VREF2 through a pull-up resistor; the internal pull-down holds it at about 0.55 V when driven low.
7 SCL2 bidirectional I2C SCL line on side 2, which must be connected to VREF2 through a pull-up resistor; the internal pull-down holds it at about 0.55 V when driven low.
8 VREF2 power_in Side-2 and device supply voltage of 2.2 V to 5.5 V; the output drivers stay off until VREF2 exceeds 2.2 V and the internal references settle (about 400 µs).
