CD4051BPWR

Texas Instruments · Analog Switches, Multiplexers · TSSOP-16

CD4051BPWR 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 CH4 bidirectional Channel 4 in/out. Analog signal path to/from COM when address A/B/C = 100 and INH = 0. rON typ 125 Ω at VDD=15V.
2 CH6 bidirectional Channel 6 in/out. Analog signal path to/from COM when address A/B/C = 110 and INH = 0.
3 COM bidirectional Common out/in. Bidirectional analog common terminal connected to the selected channel (CH0-CH7) when INH = 0.
4 CH7 bidirectional Channel 7 in/out. Analog signal path to/from COM when address A/B/C = 111 and INH = 0.
5 CH5 bidirectional Channel 5 in/out. Analog signal path to/from COM when address A/B/C = 101 and INH = 0.
6 INH input Inhibit input. When high, disables all channels (all switches OFF). When low, the channel selected by A/B/C is connected to COM. Digital logic input referenced to VSS/VDD; VIH ≥ 11V at VDD=15V.
7 VEE power_in Negative analog supply input. Sets the lower bound of the analog signal range. For single-supply operation tie to VSS; for dual-supply operation typically −5V to −10V. VDD−VEE ≤ 20V.
8 VSS power_in Ground / digital logic reference. Reference for the A/B/C/INH digital control inputs.
9 C input Channel select C (MSB of the 3-bit channel address). Digital logic input; combined with A and B selects one of CH0-CH7 when INH = 0.
10 B input Channel select B (middle bit of the 3-bit channel address). Digital logic input.
11 A input Channel select A (LSB of the 3-bit channel address). Digital logic input.
12 CH3 bidirectional Channel 3 in/out. Analog signal path to/from COM when address A/B/C = 011 and INH = 0.
13 CH0 bidirectional Channel 0 in/out. Analog signal path to/from COM when address A/B/C = 000 and INH = 0.
14 CH1 bidirectional Channel 1 in/out. Analog signal path to/from COM when address A/B/C = 001 and INH = 0.
15 CH2 bidirectional Channel 2 in/out. Analog signal path to/from COM when address A/B/C = 010 and INH = 0.
16 VDD power_in Positive supply input. 3V to 20V referenced to VSS. Also serves as the digital-input high reference (VIH ≥ 0.7·VDD).
