SN74AUP1T158DCKR from Texas Instruments, in a SC-70-6. 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 | B | input | Data input B, selected when C is low (Y = inverted B); Schmitt-trigger input accepting 1.8-V LVCMOS levels, must be held at VCC or GND if unused. |
| 2 | GND | power_in | Ground. |
| 3 | A | input | Data input A, selected when C is high (Y = inverted A); Schmitt-trigger input accepting 1.8-V LVCMOS levels, must be held at VCC or GND if unused. |
| 4 | Y | output | Inverted multiplexer output with VCC-level CMOS swing and 4 mA drive at VCC = 3 V (3.1 mA at 2.3 V). |
| 5 | VCC | power_in | Supply voltage, 2.3 V to 3.6 V recommended (absolute maximum 4.6 V). |
| 6 | C | input | Common data select input: Y = B when C is low, Y = A when C is high; must be held at VCC or GND if unused. |
