PI4ULS5V202UEX

Diodes Incorporated · Translators / Level Shifters · MSOP-8

PI4ULS5V202UEX from Diodes Incorporated, in a MSOP-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 A-port supply voltage. Configurable from 1.2 V to 5.5 V; sets the logic reference for the A1/A2 I/O pins.
2 A1 bidirectional Input/output A, channel 1. Referenced to VCCA with integrated 10 kΩ pull-up. Auto-senses direction; suitable for push-pull or open-drain (I2C/SMBus) signaling.
3 A2 bidirectional Input/output A, channel 2. Referenced to VCCA with integrated 10 kΩ pull-up. Auto-senses direction; pairs with B2 across the isolation barrier.
4 GND power_in Ground reference for both supplies and all I/O pins.
5 EN input Output enable, active HIGH. Referenced to VCCA (VIH ≥ VCCA − 0.2 V, VIL ≤ 0.15 V). Pull LOW to place all A/B outputs in high-impedance 3-state mode.
6 B2 bidirectional Input/output B, channel 2. Referenced to VCCB with integrated 10 kΩ pull-up. Auto-senses direction; pairs with A2.
7 B1 bidirectional Input/output B, channel 1. Referenced to VCCB with integrated 10 kΩ pull-up. Auto-senses direction; pairs with A1.
8 VCCB power_in B-port supply voltage. Configurable from 1.2 V to 5.5 V; sets the logic reference for the B1/B2 I/O pins. May be higher, lower, or equal to VCCA.
