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.
