SN74AUP1T158DCKR

Texas Instruments · Signal Switches, Multiplexers, Decoders · SC-70-6

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.
