SN74LVCC3245ADBR from Texas Instruments, in a SSOP-24-208mil. 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; recommended operating range 2.3 V to 3.6 V for level-translation from 2.3-3.6 V domain. |
| 2 | DIR | input | Direction control input; logic level low selects B-to-A transfer, high selects A-to-B transfer; referenced to VCCA. |
| 3 | A1 | bidirectional | A port channel 1 bidirectional I/O; operates 0 to VCCA; transfers data with B1 based on DIR and OE controls. |
| 4 | A2 | bidirectional | A port channel 2 bidirectional I/O; operates 0 to VCCA; transfers data with B2 based on DIR and OE controls. |
| 5 | A3 | bidirectional | A port channel 3 bidirectional I/O; operates 0 to VCCA; transfers data with B3 based on DIR and OE controls. |
| 6 | A4 | bidirectional | A port channel 4 bidirectional I/O; operates 0 to VCCA; transfers data with B4 based on DIR and OE controls. |
| 7 | A5 | bidirectional | A port channel 5 bidirectional I/O; operates 0 to VCCA; transfers data with B5 based on DIR and OE controls. |
| 8 | A6 | bidirectional | A port channel 6 bidirectional I/O; operates 0 to VCCA; transfers data with B6 based on DIR and OE controls. |
| 9 | A7 | bidirectional | A port channel 7 bidirectional I/O; operates 0 to VCCA; transfers data with B7 based on DIR and OE controls. |
| 10 | A8 | bidirectional | A port channel 8 bidirectional I/O; operates 0 to VCCA; transfers data with B8 based on DIR and OE controls. |
| 11 | GND | power_in | Ground; circuit common reference. |
| 12 | GND | power_in | Ground; circuit common reference. |
| 13 | GND | power_in | Ground; circuit common reference. |
| 14 | B8 | bidirectional | B port channel 8 bidirectional I/O; operates 0 to VCCB; transfers data with A8 based on DIR and OE controls. |
| 15 | B7 | bidirectional | B port channel 7 bidirectional I/O; operates 0 to VCCB; transfers data with A7 based on DIR and OE controls. |
| 16 | B6 | bidirectional | B port channel 6 bidirectional I/O; operates 0 to VCCB; transfers data with A6 based on DIR and OE controls. |
| 17 | B5 | bidirectional | B port channel 5 bidirectional I/O; operates 0 to VCCB; transfers data with A5 based on DIR and OE controls. |
| 18 | B4 | bidirectional | B port channel 4 bidirectional I/O; operates 0 to VCCB; transfers data with A4 based on DIR and OE controls. |
| 19 | B3 | bidirectional | B port channel 3 bidirectional I/O; operates 0 to VCCB; transfers data with A3 based on DIR and OE controls. |
| 20 | B2 | bidirectional | B port channel 2 bidirectional I/O; operates 0 to VCCB; transfers data with A2 based on DIR and OE controls. |
| 21 | B1 | bidirectional | B port channel 1 bidirectional I/O; operates 0 to VCCB; transfers data with A1 based on DIR and OE controls. |
| 22 | OE | input | Output enable input (active low); logic level low enables data transfer, high places all outputs in high-impedance state; referenced to VCCA. |
| 23 | NC | unconnected | No internal connection. |
| 24 | VCCB | power_in | B port supply voltage; recommended operating range 3 V to 5.5 V for level-translation to 3-5.5 V domain. |
