2 x 4:1 mux/demux in a 16-TSSOP — what the supply range means for the rail
The Texas Instruments SN74CB3T3253PWR is a single-supply 2 x 4:1 multiplexer/demultiplexer in a 16-TSSOP package, designed for signal routing in 2.3V to 3.6V systems. The 2.3V lower limit lets it run off a 2.5V rail with margin, while the 3.6V ceiling covers a nominal 3.3V supply including tolerance. Two independent 4:1 mux sections share the same supply and ground, giving you four selectable input channels per output in a compact footprint.
Industrial temperature range and surface-mount assembly
Rated for -40°C to 85°C, this part fits industrial control, outdoor telecom, and factory-automation backplanes where the ambient stays inside that window. The 16-TSSOP body (4.40 mm wide) is a standard surface-mount package; no special reflow profile beyond the usual lead-free recipe. ROHS3 compliant per the listing, so it ships without any of the restricted substances.
Active lifecycle — no obsolescence risk for new designs
For a BOM line that needs a 2 x 4:1 mux in a 16-TSSOP, this part is a safe selection for both prototyping and volume builds without a looming obsolescence window.
