Texas Instruments · Analog Switches, Multiplexers · TSSOP-16

TMUX4051PWR from Texas Instruments, in a TSSOP-16. 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 S4 bidirectional Source pin 4. Analog signal path to/from the common drain D when addressed by A[2:0]=100 with EN low. Bidirectional analog signal, VSS to VDD range.
2 S6 bidirectional Source pin 6. Analog signal path to/from the common drain D when addressed by A[2:0]=110 with EN low. Bidirectional analog signal, VSS to VDD range.
3 D bidirectional Drain pin (common). Common node of the 8:1 mux. Bidirectional analog signal, VSS to VDD range.
4 S7 bidirectional Source pin 7. Analog signal path to/from the common drain D when addressed by A[2:0]=111 with EN low. Bidirectional analog signal, VSS to VDD range.
5 S5 bidirectional Source pin 5. Analog signal path to/from the common drain D when addressed by A[2:0]=101 with EN low. Bidirectional analog signal, VSS to VDD range.
6 EN input Active-low enable (EN). When high, all internal switches are OFF. When low, the A[2:0] address selects which source pin connects to D. 1.8V-compatible logic input.
7 VSS power_in Negative power supply, most negative supply potential. Bypass with 0.1µF-10µF decoupling capacitor between VSS and GND. For single-supply operation, tie to GND.
8 GND power_in Ground (0V) reference.
9 A2 input Address line 2 (MSB). Digital select input for the 1-of-8 decoder that steers a source pin to D. 1.8V-compatible logic input.
10 A1 input Address line 1. Digital select input for the 1-of-8 decoder that steers a source pin to D. 1.8V-compatible logic input.
11 A0 input Address line 0 (LSB). Digital select input for the 1-of-8 decoder that steers a source pin to D. 1.8V-compatible logic input.
12 S3 bidirectional Source pin 3. Analog signal path to/from the common drain D when addressed by A[2:0]=011 with EN low. Bidirectional analog signal, VSS to VDD range.
13 S0 bidirectional Source pin 0. Analog signal path to/from the common drain D when addressed by A[2:0]=000 with EN low. Bidirectional analog signal, VSS to VDD range.
14 S1 bidirectional Source pin 1. Analog signal path to/from the common drain D when addressed by A[2:0]=001 with EN low. Bidirectional analog signal, VSS to VDD range.
15 S2 bidirectional Source pin 2. Analog signal path to/from the common drain D when addressed by A[2:0]=010 with EN low. Bidirectional analog signal, VSS to VDD range.
16 VDD power_in Positive power supply, most positive supply potential. Single-supply range 5V-24V; dual-supply up to ±12V. Bypass with 0.1µF-10µF decoupling capacitor between VDD and GND.
