SN74CBTLV3383PWR from Texas Instruments, in a TSSOP-24. 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, all switches are turned off, and when low, the BX pin controls the signal path selection. |
| 2 | 1B1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 3 | 1A1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 4 | 1A2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 5 | 1B2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 6 | 2B1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 7 | 2A1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 8 | 2A2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 9 | 2B2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 10 | 3B1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 11 | 3A1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 12 | GND | power_in | Ground (0 V) reference. |
| 13 | BX | input | Controls the state of the switches; with BE low, BX high selects bus-exchange (A and B pairs swapped) and BX low selects bus-switch operation. |
| 14 | 3A2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 15 | 3B2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 16 | 4B1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 17 | 4A1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 18 | 4A2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 19 | 4B2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 20 | 5B1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 21 | 5A1 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 22 | 5A2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 23 | 5B2 | bidirectional | Signal path that can be an input or output, routed through the FET switch to its paired port. |
| 24 | VCC | power_in | Positive power supply, operating from 2.3 V to 3.6 V per the recommended operating conditions. |
