74AVCH4T245BQ-Q10X from Nexperia, in a DHVQFN-16-EP(2.5x3.5). 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 | VCC(A) | power_in | Supply voltage A, 0.8 V to 3.6 V; the nAn, nOE and nDIR inputs are referenced to VCC(A). |
| 2 | 1DIR | input | Direction control for the 1A/1B channels; HIGH allows transmission from nAn to nBn and LOW allows transmission from nBn to nAn. |
| 3 | 2DIR | input | Direction control for the 2A/2B channels; HIGH allows transmission from nAn to nBn and LOW allows transmission from nBn to nAn. |
| 4 | 1A1 | bidirectional | Data input or output, referenced to VCC(A); outputs go to high-impedance OFF-state when 1OE is HIGH. |
| 5 | 1A2 | bidirectional | Data input or output, referenced to VCC(A); outputs go to high-impedance OFF-state when 1OE is HIGH. |
| 6 | 2A1 | bidirectional | Data input or output, referenced to VCC(A); outputs go to high-impedance OFF-state when 2OE is HIGH. |
| 7 | 2A2 | bidirectional | Data input or output, referenced to VCC(A); outputs go to high-impedance OFF-state when 2OE is HIGH. |
| 8 | GND | power_in | Ground (0 V); all GND pins must be connected to ground. |
| 9 | GND | power_in | Ground (0 V); all GND pins must be connected to ground. |
| 10 | 2B2 | bidirectional | Data input or output, referenced to VCC(B); outputs go to high-impedance OFF-state when 2OE is HIGH. |
| 11 | 2B1 | bidirectional | Data input or output, referenced to VCC(B); outputs go to high-impedance OFF-state when 2OE is HIGH. |
| 12 | 1B2 | bidirectional | Data input or output, referenced to VCC(B); outputs go to high-impedance OFF-state when 1OE is HIGH. |
| 13 | 1B1 | bidirectional | Data input or output, referenced to VCC(B); outputs go to high-impedance OFF-state when 1OE is HIGH. |
| 14 | 2OE | input | Output enable input for the 2 channels, active LOW; HIGH places the nAn and nBn outputs in high-impedance OFF-state. |
| 15 | 1OE | input | Output enable input for the 1 channels, active LOW; HIGH places the nAn and nBn outputs in high-impedance OFF-state. |
| 16 | VCC(B) | power_in | Supply voltage B, 0.8 V to 3.6 V; the nBn inputs are referenced to VCC(B). |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
