Function and parametric fit
The SN74CB3T3125PW is a 4-bit bus switch from TI's 74CB series, configured as four independent 1:1 SPST switches. Each switch passes digital or analog signals up to the supply rail with minimal propagation delay. The supplier device package is 14-TSSOP, surface-mount only.
RoHS3 compliant (ROHS3 Compliant) with no exemption conflicts for EU or global assembly lines. The part ships in a tube, not tape-and-reel — factor this into pick-and-place feeder setup.
Sourcing and availability
Texas Instruments is the sole manufacturer. Quoted to order against BOM quantity; availability and current pricing confirmed at RFQ through independent distribution channels. The 74CB family includes other bus switches with different circuit counts or supply ranges — verify the 4-channel, 2.3–3.6 V requirement before substituting.
