PI3B3126LEX from Diodes Incorporated, in a TSSOP-14. 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 | BE0 | input | Active-HIGH bus enable for switch 0 on the PI3B3126; driving it high connects A0 to B0, and driving it low puts the switch in high impedance (disconnect). |
| 2 | A0 | bidirectional | Bus A, bit 0 port of the 5Ω bus switch, which connects to B0 when BE0 is enabled. |
| 3 | B0 | bidirectional | Bus B, bit 0 port of the 5Ω bus switch, which connects to A0 when BE0 is enabled. |
| 4 | BE1 | input | Active-HIGH bus enable for switch 1 on the PI3B3126; driving it high connects A1 to B1, and driving it low puts the switch in high impedance (disconnect). |
| 5 | A1 | bidirectional | Bus A, bit 1 port of the 5Ω bus switch, which connects to B1 when BE1 is enabled. |
| 6 | B1 | bidirectional | Bus B, bit 1 port of the 5Ω bus switch, which connects to A1 when BE1 is enabled. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | B2 | bidirectional | Bus B, bit 2 port of the 5Ω bus switch, which connects to A2 when BE2 is enabled. |
| 9 | A2 | bidirectional | Bus A, bit 2 port of the 5Ω bus switch, which connects to B2 when BE2 is enabled. |
| 10 | BE2 | input | Active-HIGH bus enable for switch 2 on the PI3B3126; driving it high connects A2 to B2, and driving it low puts the switch in high impedance (disconnect). |
| 11 | B3 | bidirectional | Bus B, bit 3 port of the 5Ω bus switch, which connects to A3 when BE3 is enabled. |
| 12 | A3 | bidirectional | Bus A, bit 3 port of the 5Ω bus switch, which connects to B3 when BE3 is enabled. |
| 13 | BE3 | input | Active-HIGH bus enable for switch 3 on the PI3B3126; driving it high connects A3 to B3, and driving it low puts the switch in high impedance (disconnect). |
| 14 | VCC | power_in | 3.3V supply (VCC = 3.3V ±10% over the operating range); the datasheet gives an absolute maximum supply of -0.5V to +4.6V. |
