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.
