CD4051BM-JSM

JSMSEMI · Analog Switches, Multiplexers · SOP-16

CD4051BM-JSM from JSMSEMI, in a SOP-16. 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 4 bidirectional Analog channel 4 input/output of the 8-channel switch.
2 6 bidirectional Analog channel 6 input/output of the 8-channel switch.
3 COM OUT/IN bidirectional Common analog output/input shared by all eight channels.
4 7 bidirectional Analog channel 7 input/output of the 8-channel switch.
5 5 bidirectional Analog channel 5 input/output of the 8-channel switch.
6 INH input Inhibit control input; a logic 1 turns all channels off.
7 VEE power_in Negative analog supply, which sets the lower limit of the analog signal range (e.g. -5V with VDD=5V).
8 VSS power_in Ground / digital logic reference supply.
9 C input Binary channel-address select input C (with A and B selects one of eight channels).
10 B input Binary channel-address select input B.
11 A input Binary channel-address select input A.
12 3 bidirectional Analog channel 3 input/output of the 8-channel switch.
13 0 bidirectional Analog channel 0 input/output of the 8-channel switch.
14 1 bidirectional Analog channel 1 input/output of the 8-channel switch.
15 2 bidirectional Analog channel 2 input/output of the 8-channel switch.
16 VDD power_in Positive supply; recommended +5V to +15V, absolute maximum -0.5V to +18V.
