lingxingic · Analog Switches, Multiplexers · SOT-23-6

SN74LVC1G3157DB from lingxingic, in a SOT-23-6. 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 Y1 passive Independent input/output channel 1, connected to Z when S is high; recommended switch voltage is 0 to VCC V.
2 GND power_in Ground reference (0 V).
3 Y0 passive Independent input/output channel 0, connected to Z when S is low; recommended switch voltage is 0 to VCC V.
4 Z passive Common input/output, connected to Y0 when S is low or to Y1 when S is high; switch current is rated at 32 mA capability and ±50 mA absolute maximum.
5 VCC power_in Supply voltage, recommended 1.65 V to 5.5 V; absolute maximum rating is 6.5 V.
6 S input Digital select input with Schmitt-trigger action, accepts control levels up to 5.5 V and selects Y0 (L) or Y1 (H).
