U74LVC1G157G

UTC Unisonic Tech · Analog Switches, Multiplexers · SOT-363

U74LVC1G157G from UTC Unisonic Tech, in a SOT-363. 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. CMOS logic input.

CAD (KiCad official)

  • Symbol: U74LVC1G157G
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: u74lvc1g157g-etched.step / u74lvc1g157g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); u74lvc1g157g.step / u74lvc1g157g.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UTC Unisonic Tech datasheet (5 pp, sha256 0b32c07d4d4a1f4a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
