SN74CBTLV3383DBQR from Texas Instruments, in a SSOP-24-150mil. 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 | BE | input | Active-low enable; when high, disables all switches; when low, BX controls signal path selection. |
| 2 | 1B1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 3 | 1A1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 4 | 1A2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 5 | 1B2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 6 | 2B1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 7 | 2A1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 8 | 2A2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 9 | 2B2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 10 | 3B1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 11 | 3A1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 12 | GND | power_in | Ground (0V) reference for power supply. |
| 13 | BX | input | Bus exchange select; high exchanges signal pairs, low connects directly when BE is low. |
| 14 | 3A2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 15 | 3B2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 16 | 4B1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 17 | 4A1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 18 | 4A2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 19 | 4B2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 20 | 5B1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 21 | 5A1 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 22 | 5A2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 23 | 5B2 | bidirectional | Bidirectional signal path; input or output with 5Ω typical on-state resistance. |
| 24 | VCC | power_out | Positive power supply; operating range 2.3V to 3.6V. |
