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 | I1 | input | Data input 1. Routed to output Y when select S=H. CMOS logic input, VIH/VIL scale with VCC (1.65V-5.5V). |+| 2 | GND | power_in | Ground reference (0V). |+| 3 | I0 | input | Data input 0. Routed to output Y when select S=L. CMOS logic input, VIH/VIL scale with VCC (1.65V-5.5V). |+| 4 | Y | output | Multiplexer output. Drives ±24mA at VCC=3.0V (up to ±32mA at VCC=4.5V). Output = I0 when S=L, output = I1 when S=H. |+| 5 | VCC | power_in | Positive supply voltage, 1.65V to 5.5V (operating). Absolute max -0.5V to +6.5V. Quiescent current ICC ≤ 10μA. |+| 6 | S | input | Data select input. S=L selects I0 to output Y; S=H selects I1 to output Y.
