RS244YS20 from Jiangsu RUNIC Tech, in a SOP-20. 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 | 1OE | input | Active-low output enable for the 1Y outputs; pulling it HIGH places all 1Y outputs in the high-impedance 3-state mode. |
| 2 | 1A0 | input | Non-inverting data input of the 1A0 channel, passed to its Y output when the output enable is LOW. |
| 3 | 2Y0 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 4 | 1A1 | input | Non-inverting data input of the 1A1 channel, passed to its Y output when the output enable is LOW. |
| 5 | 2Y1 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 6 | 1A2 | input | Non-inverting data input of the 1A2 channel, passed to its Y output when the output enable is LOW. |
| 7 | 2Y2 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 8 | 1A3 | input | Non-inverting data input of the 1A3 channel, passed to its Y output when the output enable is LOW. |
| 9 | 2Y3 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 10 | GND | power_in | Ground reference for the device. |
| 11 | 2A3 | input | Non-inverting data input of the 2A3 channel, passed to its Y output when the output enable is LOW. |
| 12 | 1Y3 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 13 | 2A2 | input | Non-inverting data input of the 2A2 channel, passed to its Y output when the output enable is LOW. |
| 14 | 1Y2 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 15 | 2A1 | input | Non-inverting data input of the 2A1 channel, passed to its Y output when the output enable is LOW. |
| 16 | 1Y1 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 17 | 2A0 | input | Non-inverting data input of the 2A0 channel, passed to its Y output when the output enable is LOW. |
| 18 | 1Y0 | output | 3-state buffered output that follows its A-port input when enabled and goes high-impedance when its output enable is HIGH. |
| 19 | 2OE | input | Active-low output enable for the 2Y outputs; pulling it HIGH places all 2Y outputs in the high-impedance 3-state mode. |
| 20 | VCC | power_in | Supply voltage, specified from 1.65 V to 5.5 V. |
