RS0202XM

Jiangsu RUNIC Tech · Translators / Level Shifters · MSOP-8

RS0202XM from Jiangsu RUNIC Tech, 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 B2 bidirectional Input/output B2 on the B (higher-voltage) port. Referenced to VCCB (1.65 V to 5.5 V). Bidirectional level-translated data line paired with A2; direction is auto-sensed by the internal one-shot logic.
2 GND power_in Device ground return for both supply rails.
3 VCCA power_in A-port supply voltage, 1.2 V <= VCCA <= 3.6 V and VCCA <= VCCB. Sets the logic levels for the A-side I/Os (A1, A2) and the OE input threshold. Absolute max 4.6 V.
4 A2 bidirectional Input/output A2 on the A (lower-voltage) port. Referenced to VCCA (1.2 V to 3.6 V). Bidirectional level-translated data line paired with B2; disabled to Hi-Z when OE is low.
5 A1 bidirectional Input/output A1 on the A (lower-voltage) port. Referenced to VCCA (1.2 V to 3.6 V). Bidirectional level-translated data line paired with B1; disabled to Hi-Z when OE is low.
6 OE input Output Enable (active high), referenced to VCCA. VIH >= 0.65VCCA enables translation on both channels; pulling OE low (VIL <= 0.35VCCA) forces all A- and B-port I/Os into the high-impedance 3-state. Tie to GND through a pull-down resistor to guarantee Hi-Z during power-up/down. Absolute max 4.6 V, VIH can be driven up to 5.5 V.
7 VCCB power_in B-port supply voltage, 1.65 V <= VCCB <= 5.5 V. Sets the logic levels for the B-side I/Os (B1, B2). Must satisfy VCCB >= VCCA. Absolute max 6.5 V. No power-supply sequencing required; either VCC rail may ramp first, and if either VCC is at GND both ports are forced Hi-Z (VCC isolation).
8 B1 bidirectional Input/output B1 on the B (higher-voltage) port. Referenced to VCCB (1.65 V to 5.5 V). Bidirectional level-translated data line paired with A1; direction is auto-sensed by the internal one-shot logic.
