# CAVC2T45TDCURQ1

**Texas Instruments** · Translators, Level Shifters · VSSOP-8-0.5mm

CAVC2T45TDCURQ1 from Texas Instruments, in a VSSOP-8-0.5mm. 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 | Supply voltage for port A, specified from 1.2 V to 3.6 V; port A outputs and inputs track this supply. |
| 2 | A1 | bidirectional | Port A I/O that acts as an output or input depending on DIR, with output levels referenced to VCCA; I/O tolerates up to 4.6 V. |
| 3 | A2 | bidirectional | Port A I/O that acts as an output or input depending on DIR, with output levels referenced to VCCA; I/O tolerates up to 4.6 V. |
| 4 | GND | power_in | Device ground reference. |
| 5 | DIR | input | Direction control input referenced to VCCA: low selects B-to-A transfer and high selects A-to-B transfer; it must be tied to GND or VCCA and must not float. |
| 6 | B2 | bidirectional | Port B I/O that acts as an output or input depending on DIR, with output levels referenced to VCCB; I/O tolerates up to 4.6 V. |
| 7 | B1 | bidirectional | Port B I/O that acts as an output or input depending on DIR, with output levels referenced to VCCB; I/O tolerates up to 4.6 V. |
| 8 | VCCB | power_in | Supply voltage for port B, specified from 1.2 V to 3.6 V; port B outputs and inputs track this supply. |
