MUX506IDWR

Texas Instruments · Analog Switches, Multiplexers · SOIC-28-300mil

MUX506IDWR from Texas Instruments, in a SOIC-28-300mil. 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 VDD power_in Positive power supply; most positive power-supply potential; connect 0.1 µF to 10 µF decoupling capacitor between VDD and GND.
2 NC unconnected No connect; do not connect.
3 NC unconnected No connect; do not connect.
4 S16 bidirectional Source pin 16 for 16:1 multiplexer operation; can be input or output.
5 S15 bidirectional Source pin 15 for 16:1 multiplexer operation; can be input or output.
6 S14 bidirectional Source pin 14 for 16:1 multiplexer operation; can be input or output.
7 S13 bidirectional Source pin 13 for 16:1 multiplexer operation; can be input or output.
8 S12 bidirectional Source pin 12 for 16:1 multiplexer operation; can be input or output.
9 S11 bidirectional Source pin 11 for 16:1 multiplexer operation; can be input or output.
10 S10 bidirectional Source pin 10 for 16:1 multiplexer operation; can be input or output.
11 S9 bidirectional Source pin 9 for 16:1 multiplexer operation; can be input or output.
12 GND power_in Ground (0 V) reference for power supply.
13 NC unconnected No connect; do not connect.
14 A3 input Digital input address line 3 for channel selection in 16:1 multiplexer.
15 A2 input Digital input address line 2 for channel selection in 16:1 multiplexer.
16 A1 input Digital input address line 1 for channel selection in 16:1 multiplexer.
17 A0 input Digital input address line 0 for channel selection in 16:1 multiplexer.
18 EN input Active high digital enable input; when low, all switches are turned off; when high, A[3:0] determines which switch is on.
19 S1 bidirectional Source pin 1 for 16:1 multiplexer operation; can be input or output.
20 S2 bidirectional Source pin 2 for 16:1 multiplexer operation; can be input or output.
21 S3 bidirectional Source pin 3 for 16:1 multiplexer operation; can be input or output.
22 S4 bidirectional Source pin 4 for 16:1 multiplexer operation; can be input or output.
23 S5 bidirectional Source pin 5 for 16:1 multiplexer operation; can be input or output.
24 S6 bidirectional Source pin 6 for 16:1 multiplexer operation; can be input or output.
25 S7 bidirectional Source pin 7 for 16:1 multiplexer operation; can be input or output.
26 S8 bidirectional Source pin 8 for 16:1 multiplexer operation; can be input or output.
27 VSS power_in Negative power supply; most negative power-supply potential; can be connected to ground in single-supply applications; connect 0.1 µF to 10 µF decoupling capacitor between VSS and GND.
28 D bidirectional Drain pin for 16:1 multiplexer operation; can be input or output.
