74AVC4T245RSVR-NT from Texas Instruments, in a UQFN-16(1.8x2.6). 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 control input for 1-port; pull high to place outputs in 3-state mode; referenced to VCCA |
| 2 | VCCB | power_in | B-port power supply voltage; operating range 1.2V to 3.6V for bus transceiver operation |
| 3 | VCCA | power_in | A-port power supply voltage; operating range 1.2V to 3.6V for bus transceiver operation |
| 4 | 1DIR | input | Direction-control input for 1-port; logic level selects data flow direction between A and B buses |
| 5 | 2DIR | input | Direction-control input for 2-port; logic level selects data flow direction between A and B buses |
| 6 | 1A1 | bidirectional | Bidirectional data I/O port 1A1 referenced to VCCA; ±50mA continuous source/sink current capability |
| 7 | 1A2 | bidirectional | Bidirectional data I/O port 1A2 referenced to VCCA; ±50mA continuous source/sink current capability |

Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm - 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
