SN74AVCH1T45DBVR 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, 1.2 V ≤ VCCA ≤ 3.6 V |
| 2 | GND | power_in | Ground |
| 3 | A | bidirectional | Input/output A, referenced to VCCA, with active bus-hold circuitry |
| 4 | B | bidirectional | Input/output B, referenced to VCCB, with active bus-hold circuitry |
| 5 | DIR | input | Direction control signal referenced to VCCA; high enables A to B transmission, low enables B to A transmission |
| 6 | VCCB | power_in | B-port supply voltage, 1.2 V ≤ VCCB ≤ 3.6 V |
