Texas Instruments · Analog Switches, Multiplexers · UQFN-10(1.4x1.8)

TMUXHS221NKGR from Texas Instruments, in a UQFN-10(1.4x1.8). 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 D+ bidirectional Common port positive data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
2 D- bidirectional Common port negative data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
3 GND power_in Ground reference
4 DA- bidirectional Port A negative data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
5 DA+ bidirectional Port A positive data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
6 DB- bidirectional Port B negative data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
7 DB+ bidirectional Port B positive data signal; bidirectional signal with voltage range -0.3 to 3.6 V, 5 V tolerant
8 OEn input Output enable control, active low; control input with voltage range -0.3 to 4.0 V
9 VCC power_in 3.3 V power supply with recommended operating range 3.0 to 3.6 V
10 SEL input Mux configuration select control input with voltage range -0.3 to 4.0 V; selects D to DA (low) or D to DB (high)

CAD (KiCad official)

  • Symbol: TMUXHS221NKGR
  • Footprint: Package_DFN_QFN:UQFN-10_1.4x1.8mm_P0.4mm
  • 3D model: UQFN-10(1.4x1.8) (KiCad packages3D, STEP)
  • 3D model files: tmuxhs221nkgr-etched.step / tmuxhs221nkgr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmuxhs221nkgr.step / tmuxhs221nkgr.glb are the bare package body.
