SN74CBT1G125DBVR from Texas Instruments, in a SOT-23-5. 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 | OE | input | TTL-compatible output-enable control input connecting ports A and B through 5-Ω switch when low (≤0.8V) or disconnecting when high (≥2V); input voltage range -0.5V to 7V absolute maximum. |
| 2 | A | bidirectional | Switch port A that conducts to port B through 5-Ω connection when OE is low or presents high impedance when OE is high; voltage range -0.5V to 7V absolute maximum. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | B | bidirectional | Switch port B that conducts to port A through 5-Ω connection when OE is low or presents high impedance when OE is high; voltage range -0.5V to 7V absolute maximum. |
| 5 | VCC | power_in | Positive supply voltage pin with recommended operating range 4V to 5.5V and absolute maximum -0.5V to 7V. |
