SN74CBT3125DBR from Texas Instruments, in a SSOP-14-208mil. 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 | Output-enable for switch 1; switch is disabled (disconnected) when high, A port = B port when low. |
| 2 | 1A | bidirectional | Switch 1 port A, connected to 1B through a 5-Ω switch when 1OE is low. |
| 3 | 1B | bidirectional | Switch 1 port B, connected to 1A through a 5-Ω switch when 1OE is low. |
| 4 | 2OE | input | Output-enable for switch 2; switch is disabled (disconnected) when high, A port = B port when low. |
| 5 | 2A | bidirectional | Switch 2 port A, connected to 2B through a 5-Ω switch when 2OE is low. |
| 6 | 2B | bidirectional | Switch 2 port B, connected to 2A through a 5-Ω switch when 2OE is low. |
| 7 | GND | power_in | Ground. |
| 8 | 3B | bidirectional | Switch 3 port B, connected to 3A through a 5-Ω switch when 3OE is low. |
| 9 | 3A | bidirectional | Switch 3 port A, connected to 3B through a 5-Ω switch when 3OE is low. |
| 10 | 3OE | input | Output-enable for switch 3; switch is disabled (disconnected) when high, A port = B port when low. |
| 11 | 4B | bidirectional | Switch 4 port B, connected to 4A through a 5-Ω switch when 4OE is low. |
| 12 | 4A | bidirectional | Switch 4 port A, connected to 4B through a 5-Ω switch when 4OE is low. |
| 13 | 4OE | input | Output-enable for switch 4; switch is disabled (disconnected) when high, A port = B port when low. |
| 14 | VCC | power_in | Supply voltage, 4 V to 5.5 V recommended (absolute maximum −0.5 V to 7 V). |
