SN74AVC2T45DCUR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · VSSOP-8

SN74AVC2T45DCUR from Texas Instruments, in a VSSOP-8. 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 the A port; A-side I/O output levels track VCCA, which the recommended operating conditions specify as 1.2 V to 3.6 V.
2 A1 bidirectional Input or output depending on the DIR state; the output level is referenced to VCCA.
3 A2 bidirectional Input or output depending on the DIR state; the output level is referenced to VCCA.
4 GND power_in Device ground; if either VCC input is tied to GND, both ports are placed in the high-impedance state.
5 DIR input Direction control input connected to GND or VCCA; DIR low transfers data from the B bus to the A bus and DIR high transfers data from the A bus to the B bus.
6 B2 bidirectional Input or output depending on the DIR state; the output level is referenced to VCCB.
7 B1 bidirectional Input or output depending on the DIR state; the output level is referenced to VCCB.
8 VCCB power_in Supply voltage for the B port; B-side I/O output levels track VCCB, which the recommended operating conditions specify as 1.2 V to 3.6 V.
