Product details

Single-bit bus switch for 5 V digital paths

The Texas Instruments SN74CBT1G125DBVT is a single-pole, single-throw bus switch in a 5-pin SOT-23-5 package. It connects or isolates one digital signal path under the control of a single enable input, with a 1:1 circuit topology. The part operates from a 4.5 V to 5.5 V supply and is rated over the industrial temperature range of -40°C to 85°C, suiting it for factory automation, telecom line cards, and general-purpose PCB-level signal routing where a narrow 5 V bus is present.

Lifecycle and sourcing reality

The SN74CBT1G125DBVT carries an Active lifecycle status with ROHS3 compliance. There is no NRND flag, no last-time-buy notice, and no official successor listed — TI continues to manufacture this part for new and existing designs.

Frequently asked questions

What is the difference between SN74CBT1G125DBVT and SN74CBT1G125DBVR?

Both are the same die and function. The DBVT suffix indicates Tape & Reel packaging, while DBVR indicates Cut Tape (CT) packaging. Electrical specs and footprint are identical.

Can SN74CBT1G125DBVT be used as a level shifter?

No — this is a pass-gate bus switch, not a level translator. The supply voltage sets the pass voltage; with a 5 V rail, the switch passes signals near 5 V. For level shifting between different voltage domains, use a dedicated level translator or a bus switch with integrated translation.
