SN74AXC1T45DCKR

Texas Instruments · Translators, Level Shifters · SC-70-6

SN74AXC1T45DCKR from Texas Instruments, in a SC-70-6. 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 A-port supply voltage; 0.65 V ≤ VCCA ≤ 3.6 V.
2 GND power_in Ground reference.
3 A bidirectional Input or output A, referenced to VCCA; do not leave floating when configured as input.
4 B bidirectional Input or output B, referenced to VCCB; do not leave floating when configured as input.
5 DIR input Direction control signal; logic high for A-to-B level translation, logic low for B-to-A level translation.
6 VCCB power_in B-port supply voltage; 0.65 V ≤ VCCB ≤ 3.6 V.
