CD74HCT138M96 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 | A0 | input | Address input 0; selects one of eight outputs in conjunction with A1 and A2. |
| 2 | A1 | input | Address input 1; selects one of eight outputs in conjunction with A0 and A2. |
| 3 | A2 | input | Address input 2; selects one of eight outputs in conjunction with A0 and A1. |
| 4 | G0 | input | Active-low output strobe 0; combined with G1 and G2 for output enable control. |
| 5 | G1 | input | Active-low output strobe 1; combined with G0 and G2 for output enable control. |
| 6 | G2 | input | Output strobe 2; combined with G0 and G1 for output enable and decoder cascading. |
| 7 | Y7 | output | Active-low decoder output 7; selected when A2=1, A1=1, A0=1. |
| 8 | GND | power_in | Ground reference potential. |
| 9 | Y6 | output | Active-low decoder output 6; selected when A2=1, A1=1, A0=0. |
| 10 | Y5 | output | Active-low decoder output 5; selected when A2=1, A1=0, A0=1. |
| 11 | Y4 | output | Active-low decoder output 4; selected when A2=1, A1=0, A0=0. |
| 12 | Y3 | output | Active-low decoder output 3; selected when A2=0, A1=1, A0=1. |
| 13 | Y2 | output | Active-low decoder output 2; selected when A2=0, A1=1, A0=0. |
| 14 | Y1 | output | Active-low decoder output 1; selected when A2=0, A1=0, A0=1. |
| 15 | Y0 | output | Active-low decoder output 0; selected when A2=0, A1=0, A0=0. |
| 16 | VCC | power_in | Positive supply voltage; recommended operating range 4.5V to 5.5V for HCT138. |
