Texas Instruments · Signal Switches, Multiplexers, Decoders · SOIC-16

CD4556BM96 from Texas Instruments, in a SOIC-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 E1 input Enable input (active-low symbol E-bar) of decoder 1; when high all outputs of the CD4556B remain high regardless of A and B.
2 A1 input Select input A of decoder 1; input voltage range -0.5V to VDD+0.5V.
3 B1 input Select input B of decoder 1; input voltage range -0.5V to VDD+0.5V.
4 Q0_1 output Decoder 1 output Q0-bar, low when selected (A=0, B=0, E=0) on the CD4556B.
5 Q1_1 output Decoder 1 output Q1-bar, low when selected (A=1, B=0, E=0) on the CD4556B.
6 Q2_1 output Decoder 1 output Q2-bar, low when selected (A=0, B=1, E=0) on the CD4556B.
7 Q3_1 output Decoder 1 output Q3-bar, low when selected (A=1, B=1, E=0) on the CD4556B.
8 VSS power_in Ground / negative supply terminal; voltages are referenced to VSS.
9 Q3_2 output Decoder 2 output Q3-bar, low when selected (A=1, B=1, E=0) on the CD4556B.
10 Q2_2 output Decoder 2 output Q2-bar, low when selected (A=0, B=1, E=0) on the CD4556B.
11 Q1_2 output Decoder 2 output Q1-bar, low when selected (A=1, B=0, E=0) on the CD4556B.
12 Q0_2 output Decoder 2 output Q0-bar, low when selected (A=0, B=0, E=0) on the CD4556B.
13 B2 input Select input B of decoder 2; input voltage range -0.5V to VDD+0.5V.
14 A2 input Select input A of decoder 2; input voltage range -0.5V to VDD+0.5V.
15 E2 input Enable input (E-bar) of decoder 2; when high all outputs of the CD4556B remain high regardless of A and B.
16 VDD power_in Positive supply; recommended 3V to 18V, absolute maximum -0.5V to +20V referenced to VSS.
