Texas Instruments · Analog Switches, Multiplexers · UQFN-16(1.8x2.6)

TMUX1109RSVR from Texas Instruments, in a UQFN-16(1.8x2.6). 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 VSS power_in Negative power supply potential; connect decoupling capacitor 0.1µF to 10µF between VSS and GND for reliable operation; VSS can be connected to ground for single supply applications.
2 S1A bidirectional Source pin 1A; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
3 S2A bidirectional Source pin 2A; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
4 S3A bidirectional Source pin 3A; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
5 S4A bidirectional Source pin 4A; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
6 DA bidirectional Drain pin A; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
7 DB bidirectional Drain pin B; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
8 S4B bidirectional Source pin 4B; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
9 S3B bidirectional Source pin 3B; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
10 S2B bidirectional Source pin 2B; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
11 S1B bidirectional Source pin 1B; supports bidirectional analog and digital signals from VSS to VDD with low on-resistance 1.8Ω and low charge injection 1pC.
12 VDD power_in Positive power supply potential; connect decoupling capacitor 0.1µF to 10µF between VDD and GND for reliable operation; supports 1.08V to 5.5V single supply or ±2.75V dual supply.
13 GND power_in Ground (0V) reference for analog and digital signal paths.
14 A1 input Address line 1; active high logic input with 1.8V logic level compatibility; controls switch configuration in conjunction with A0.
15 A0 input Address line 0; active high logic input with 1.8V logic level compatibility; controls switch configuration in conjunction with A1.
16 EN input Enable; active high logic input with 1.8V logic level compatibility; when low all switches are turned off; when high A[1:0] address inputs determine which switch is turned on.

CAD (KiCad official)

  • Symbol: TMUX1109RSVR
  • Footprint: Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm
  • 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tmux1109rsvr-etched.step / tmux1109rsvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmux1109rsvr.step / tmux1109rsvr.glb are the bare package body.
