TMUX1574RSVR

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

TMUX1574RSVR 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 S1B bidirectional Source pin 1B; bidirectional signal path supporting analog and digital signals.
2 D1 bidirectional Drain pin 1; bidirectional signal path supporting analog and digital signals.
3 S2A bidirectional Source pin 2A; bidirectional signal path supporting analog and digital signals.
4 S2B bidirectional Source pin 2B; bidirectional signal path supporting analog and digital signals.
5 D2 bidirectional Drain pin 2; bidirectional signal path supporting analog and digital signals.
6 GND power_in Ground (0 V) reference.
7 D3 bidirectional Drain pin 3; bidirectional signal path supporting analog and digital signals.
8 S3B bidirectional Source pin 3B; bidirectional signal path supporting analog and digital signals.
9 S3A bidirectional Source pin 3A; bidirectional signal path supporting analog and digital signals.
10 D4 bidirectional Drain pin 4; bidirectional signal path supporting analog and digital signals.
11 S4B bidirectional Source pin 4B; bidirectional signal path supporting analog and digital signals.
12 S4A bidirectional Source pin 4A; bidirectional signal path supporting analog and digital signals.
13 EN input Active-low enable pin; when high all switches turn off, when low SEL controls signal path selection; internal 6 MΩ pull-down to GND.
14 VDD power_in Positive power supply (1.5 V to 5.5 V); requires 0.1 µF to 10 µF decoupling capacitor to GND.
15 SEL input Select pin controlling state of all four 2:1 SPDT switches; internal 6 MΩ pull-down to GND.
16 S1A bidirectional Source pin 1A; bidirectional signal path supporting analog and digital signals.

CAD (KiCad official)

  • Symbol: TMUX1574RSVR
  • 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: tmux1574rsvr-etched.step / tmux1574rsvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmux1574rsvr.step / tmux1574rsvr.glb are the bare package body.
