SN74LVC1T45MDCKREP

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

SN74LVC1T45MDCKREP 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 Supply for the A port, which accepts any voltage from 1.65 V to 5.5 V and sets the A-port logic levels and the DIR input reference.
2 GND power_in Device ground; per the power-up guidance, ground must be connected before any supply voltage is applied.
3 A bidirectional A-port data I/O that tracks VCCA; A-port output voltage is limited to -0.5 V to VCCA + 0.5 V in the high or low state.
4 B bidirectional B-port data I/O that tracks VCCB; B-port output voltage is limited to -0.5 V to VCCB + 0.5 V in the high or low state.
5 DIR input Direction control referenced to VCCA: a low level selects B-to-A transfer and a high level selects A-to-B transfer; the input voltage range is 0 to 5.5 V.
6 VCCB power_in Supply for the B port, which accepts any voltage from 1.65 V to 5.5 V and sets the B-port logic levels.
