SN74CBT3384ADW from Texas Instruments, in a SOIC-24-300mil. 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 | 1OE | input | Active-low output enable for the first 5-bit switch; low connects 1A to 1B, high opens the switch to high impedance. |
| 2 | 1B1 | bidirectional | Port B bit 1 of the first 5-bit switch, connected to 1A1 through the switch when 1OE is low. |
| 3 | 1A1 | bidirectional | Port A bit 1 of the first 5-bit switch, connected to 1B1 through the switch when 1OE is low. |
| 4 | 1A2 | bidirectional | Port A bit 2 of the first 5-bit switch, connected to 1B2 through the switch when 1OE is low. |
| 5 | 1B2 | bidirectional | Port B bit 2 of the first 5-bit switch, connected to 1A2 through the switch when 1OE is low. |
| 6 | 1B3 | bidirectional | Port B bit 3 of the first 5-bit switch, connected to 1A3 through the switch when 1OE is low. |
| 7 | 1A3 | bidirectional | Port A bit 3 of the first 5-bit switch, connected to 1B3 through the switch when 1OE is low. |
| 8 | 1A4 | bidirectional | Port A bit 4 of the first 5-bit switch, connected to 1B4 through the switch when 1OE is low. |
| 9 | 1B4 | bidirectional | Port B bit 4 of the first 5-bit switch, connected to 1A4 through the switch when 1OE is low. |
| 10 | 1B5 | bidirectional | Port B bit 5 of the first 5-bit switch, connected to 1A5 through the switch when 1OE is low. |
| 11 | 1A5 | bidirectional | Port A bit 5 of the first 5-bit switch, connected to 1B5 through the switch when 1OE is low. |
| 12 | GND | power_in | Ground. |
| 13 | 2OE | input | Active-low output enable for the second 5-bit switch; low connects 2A to 2B, high opens the switch to high impedance. |
| 14 | 2A1 | bidirectional | Port A bit 1 of the second 5-bit switch, connected to 2B1 through the switch when 2OE is low. |
| 15 | 2B1 | bidirectional | Port B bit 1 of the second 5-bit switch, connected to 2A1 through the switch when 2OE is low. |
| 16 | 2B2 | bidirectional | Port B bit 2 of the second 5-bit switch, connected to 2A2 through the switch when 2OE is low. |
| 17 | 2A2 | bidirectional | Port A bit 2 of the second 5-bit switch, connected to 2B2 through the switch when 2OE is low. |
| 18 | 2A3 | bidirectional | Port A bit 3 of the second 5-bit switch, connected to 2B3 through the switch when 2OE is low. |
| 19 | 2B3 | bidirectional | Port B bit 3 of the second 5-bit switch, connected to 2A3 through the switch when 2OE is low. |
| 20 | 2B4 | bidirectional | Port B bit 4 of the second 5-bit switch, connected to 2A4 through the switch when 2OE is low. |
| 21 | 2A4 | bidirectional | Port A bit 4 of the second 5-bit switch, connected to 2B4 through the switch when 2OE is low. |
| 22 | 2A5 | bidirectional | Port A bit 5 of the second 5-bit switch, connected to 2B5 through the switch when 2OE is low. |
| 23 | 2B5 | bidirectional | Port B bit 5 of the second 5-bit switch, connected to 2A5 through the switch when 2OE is low. |
| 24 | VCC | power_in | Supply voltage, recommended 4 V to 5.5 V (absolute maximum -0.5 V to 7 V). |
