SN74AVCH2T45DCUR

Texas Instruments · Translators, Level Shifters · VSSOP-8

SN74AVCH2T45DCUR from Texas Instruments, in a VSSOP-8. 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 Supply voltage A for port A, operating range 1.2V to 3.6V per section 5.3.
2 A1 bidirectional Port A bit 1, bidirectional I/O with output level dependent on VCCA; direction controlled by DIR input.
3 A2 bidirectional Port A bit 2, bidirectional I/O with output level dependent on VCCA; direction controlled by DIR input.
4 GND power_in Device ground reference.
5 DIR input Direction control input referenced to VCCA; logic low selects B-to-A data transfer, logic high selects A-to-B data transfer.
6 B2 bidirectional Port B bit 2, bidirectional I/O with output level dependent on VCCB; direction controlled by DIR input.
7 B1 bidirectional Port B bit 1, bidirectional I/O with output level dependent on VCCB; direction controlled by DIR input.
8 VCCB power_in Supply voltage B for port B, operating range 1.2V to 3.6V per section 5.3.
