SN74LXC1T45DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | A-port supply voltage; operating range 1.1 V to 5.5 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | A | bidirectional | Input or output port A referenced to VCCA; accepts 1.1 V to 5.5 V with integrated dynamic pull-down resistor. |
| 4 | B | bidirectional | Input or output port B referenced to VCCB; accepts 1.1 V to 5.5 V with integrated dynamic pull-down resistor. |
| 5 | DIR | input | Direction-control signal referenced to VCCA; high level transmits A to B, low level transmits B to A, with integrated static pull-down resistor. |
| 6 | VCCB | power_in | B-port supply voltage; operating range 1.1 V to 5.5 V. |
