TMUX1109PWR

Texas Instruments · Analog Switches, Multiplexers · TSSOP-16-175mil

TMUX1109PWR from Texas Instruments, in a TSSOP-16-175mil. 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 A0 input Address input line 0; 1.8V logic compatible (0 to 5.5V input range) controlling switch configuration.
2 EN input Active high enable input; 1.8V logic compatible (0 to 5.5V input range); all switches turned off when low.
3 VSS power_in Negative power supply rail; connect 0.1µF to 10µF decoupling capacitor between VSS and GND for reliable operation.
4 S1A bidirectional Source signal pin 1A; rail-to-rail bidirectional signal path operating from VSS to VDD.
5 S2A bidirectional Source signal pin 2A; rail-to-rail bidirectional signal path operating from VSS to VDD.
6 S3A bidirectional Source signal pin 3A; rail-to-rail bidirectional signal path operating from VSS to VDD.
7 S4A bidirectional Source signal pin 4A; rail-to-rail bidirectional signal path operating from VSS to VDD.
8 DA bidirectional Drain signal pin A; rail-to-rail bidirectional signal path operating from VSS to VDD.
9 DB bidirectional Drain signal pin B; rail-to-rail bidirectional signal path operating from VSS to VDD.
10 S4B bidirectional Source signal pin 4B; rail-to-rail bidirectional signal path operating from VSS to VDD.
11 S3B bidirectional Source signal pin 3B; rail-to-rail bidirectional signal path operating from VSS to VDD.
12 S2B bidirectional Source signal pin 2B; rail-to-rail bidirectional signal path operating from VSS to VDD.
13 S1B bidirectional Source signal pin 1B; rail-to-rail bidirectional signal path operating from VSS to VDD.
14 VDD power_out Positive power supply rail (1.08V to 5.5V single supply or +2.75V dual supply); connect 0.1µF to 10µF decoupling capacitor to GND.
15 GND power_in Ground reference at 0V potential.
16 A1 input Address input line 1; 1.8V logic compatible (0 to 5.5V input range) controlling switch configuration.
