SN74CB3T1G125DCKR

Texas Instruments · Signal Switches, Multiplexers, Decoders · SC-70-5

SN74CB3T1G125DCKR from Texas Instruments, in a SC-70-5. 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 OE input Active-low output enable: low turns the A-B switch ON, high gives a high-impedance state between A and B; control input accepts TTL or 5-V/3.3-V CMOS levels (VIH 1.7 V min at VCC 2.3-2.7 V, 2 V min at 2.7-3.6 V, up to 5.5 V).
2 A bidirectional Bidirectional switch data I/O port A, connected to B when OE is low and supporting 0- to 5.5-V signal levels.
3 GND power_in Ground.
4 B bidirectional Bidirectional switch data I/O port B, connected to A when OE is low, with output voltage translation tracking VCC and 0- to 5.5-V signal levels.
5 VCC power_in Supply voltage, 2.3 V to 3.6 V recommended operating range (absolute maximum 7 V).

  • Symbol: SN74CB3T1G125DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: sn74cb3t1g125dckr-etched.step / sn74cb3t1g125dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74cb3t1g125dckr.step / sn74cb3t1g125dckr.glb are the bare package body.
