CD4555BPWR from Texas Instruments, in a TSSOP-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 | 1E | input | Enable input for decoder 1; when high, all outputs of that decoder go low regardless of A and B. |
| 2 | 1A | input | Select input A of decoder 1; inputs are 0.5 V to VDD+0.5 V rated. |
| 3 | 1B | input | Select input B of decoder 1; inputs are 0.5 V to VDD+0.5 V rated. |
| 4 | 1Q0 | output | Decoder 1 output Q0, active high on select. |
| 5 | 1Q1 | output | Decoder 1 output Q1, active high on select. |
| 6 | 1Q2 | output | Decoder 1 output Q2, active high on select. |
| 7 | 1Q3 | output | Decoder 1 output Q3, active high on select. |
| 8 | VSS | power_in | Ground / negative supply terminal; supply voltages are referenced to VSS. |
| 9 | 2Q3 | output | Decoder 2 output Q3, active high on select. |
| 10 | 2Q2 | output | Decoder 2 output Q2, active high on select. |
| 11 | 2Q1 | output | Decoder 2 output Q1, active high on select. |
| 12 | 2Q0 | output | Decoder 2 output Q0, active high on select. |
| 13 | 2B | input | Select input B of decoder 2; inputs are 0.5 V to VDD+0.5 V rated. |
| 14 | 2A | input | Select input A of decoder 2; inputs are 0.5 V to VDD+0.5 V rated. |
| 15 | 2E | input | Enable input for decoder 2; when high, all outputs of that decoder go low regardless of A and B. |
| 16 | VDD | power_in | Positive supply voltage, 3 V to 18 V recommended, absolute maximum -0.5 V to +20 V. |
