SN74LVCC3245ADWR from Texas Instruments, in a SOIC-24-300mil. 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 | VCCA | power_in | A-port supply voltage, operating range 2.3 V to 3.6 V; if VCCA is below 100 mV or floating, all I/O outputs are disabled and go high-impedance. |
| 2 | DIR | input | Direction control input referenced to VCCA; low transfers data from the B bus to the A bus and high transfers data from the A bus to the B bus (with OE low). |
| 3 | A1 | bidirectional | A1 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 4 | A2 | bidirectional | A2 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 5 | A3 | bidirectional | A3 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 6 | A4 | bidirectional | A4 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 7 | A5 | bidirectional | A5 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 8 | A6 | bidirectional | A6 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 9 | A7 | bidirectional | A7 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 10 | A8 | bidirectional | A8 port data I/O, tracking VCCA (2.3 V to 3.6 V). |
| 11 | GND | power_in | Ground reference; the datasheet states ground should be applied first during power-up. |
| 12 | GND | power_in | Ground reference pin. |
| 13 | GND | power_in | Ground reference pin. |
| 14 | B8 | bidirectional | B8 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 15 | B7 | bidirectional | B7 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 16 | B6 | bidirectional | B6 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 17 | B5 | bidirectional | B5 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 18 | B4 | bidirectional | B4 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 19 | B3 | bidirectional | B3 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 20 | B2 | bidirectional | B2 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 21 | B1 | bidirectional | B1 port data I/O, tracking VCCB (3 V to 5.5 V). |
| 22 | OE | input | Output enable, active low; when high the device is isolated (A and B ports disabled), and the control circuitry is powered from VCCA. |
| 23 | NC | unconnected | No internal connection. |
| 24 | VCCB | power_in | B-port supply voltage, operating range 3 V to 5.5 V; if VCCB is below 100 mV or floating, all I/O outputs are disabled and go high-impedance. |
