AiP74AVC4T774TA16.TR from Wuxi I core Elec, in a TSSOP-16. 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 | DIR1 | input | Direction control input referenced to VCC(A): HIGH allows transmission from A1 to B1 and LOW allows transmission from B1 to A1, with inputs accepting up to 3.6V. |
| 2 | DIR2 | input | Direction control input referenced to VCC(A): HIGH allows transmission from A2 to B2 and LOW allows transmission from B2 to A2, with inputs accepting up to 3.6V. |
| 3 | A1 | bidirectional | Data input or output referenced to VCC(A), operating over 0.8V to 3.6V, and placed in high-impedance when OE is HIGH or either supply is at GND. |
| 4 | A2 | bidirectional | Data input or output referenced to VCC(A), operating over 0.8V to 3.6V, and placed in high-impedance when OE is HIGH or either supply is at GND. |
| 5 | A3 | bidirectional | Data input or output referenced to VCC(A), operating over 0.8V to 3.6V, and placed in high-impedance when OE is HIGH or either supply is at GND. |
| 6 | A4 | bidirectional | Data input or output referenced to VCC(A), operating over 0.8V to 3.6V, and placed in high-impedance when OE is HIGH or either supply is at GND. |
| 7 | DIR3 | input | Direction control input referenced to VCC(A): HIGH allows transmission from A3 to B3 and LOW allows transmission from B3 to A3, with inputs accepting up to 3.6V. |
| 8 | DIR4 | input | Direction control input referenced to VCC(A): HIGH allows transmission from A4 to B4 and LOW allows transmission from B4 to A4, with inputs accepting up to 3.6V. |
| 9 | OE | input | Active-LOW output enable input referenced to VCC(A); a HIGH level places the An and Bn outputs in high-impedance, isolating the buses. |
| 10 | GND | power_in | Ground (0V) reference for the device; the device enters suspend mode if either VCC(A) or VCC(B) is at GND level. |
| 11 | B4 | bidirectional | Data input or output referenced to VCC(B), operating over 0.8V to 3.6V, and placed in high-impedance in suspend mode or when OE is HIGH. |
| 12 | B3 | bidirectional | Data input or output referenced to VCC(B), operating over 0.8V to 3.6V, and placed in high-impedance in suspend mode or when OE is HIGH. |
| 13 | B2 | bidirectional | Data input or output referenced to VCC(B), operating over 0.8V to 3.6V, and placed in high-impedance in suspend mode or when OE is HIGH. |
| 14 | B1 | bidirectional | Data input or output referenced to VCC(B), operating over 0.8V to 3.6V, and placed in high-impedance in suspend mode or when OE is HIGH. |
| 15 | VCC(B) | power_in | Supply voltage B, specified from 0.8V to 3.6V, to which the Bn inputs and outputs are referenced. |
| 16 | VCC(A) | power_in | Supply voltage A, specified from 0.8V to 3.6V, to which the An, OE and DIRn inputs are referenced. |
