SN74AXC1T45DRLR

Texas Instruments · Translators, Level Shifters · SOT-563

SN74AXC1T45DRLR from Texas Instruments, in a SOT-563. 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, which must be kept within 0.65 V to 3.6 V (0.65 V ≤ VCCA ≤ 3.6 V).
2 GND power_in Ground reference for the device.
3 A bidirectional Input or output A, referenced to VCCA; do not leave it floating when it is configured as an input.
4 B bidirectional Input or output B, referenced to VCCB; do not leave it floating when it is configured as an input.
5 DIR input Direction control: logic high selects A-to-B translation and logic low selects B-to-A translation; the DIR logic thresholds are referenced to VCCA.
6 VCCB power_in B-port supply voltage, which must be kept within 0.65 V to 3.6 V (0.65 V ≤ VCCB ≤ 3.6 V).

CAD (KiCad official)

  • Symbol: SN74AXC1T45DRLR
  • Footprint: Package_TO_SOT_SMD:SOT-563
  • 3D model: SOT-563 (KiCad packages3D, STEP)
  • 3D model files: sn74axc1t45drlr-etched.step / sn74axc1t45drlr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74axc1t45drlr.step / sn74axc1t45drlr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
