4 x 1:2 signal routing with 2.3-3.6 V single supply
The SN74CBTLV3257DR is a 4-channel 1:2 multiplexer/demultiplexer from TI's 74CBTLV family, designed for high-speed signal switching in low-voltage digital systems. Each of the four independent circuits selects one of two data inputs to a common output, or routes a common input to one of two outputs, controlled by a single select line per channel.
16-SOIC footprint and surface-mount assembly
The 1.27 mm pin pitch is compatible with 2-layer PCB routing — no via fan-out required for the inner pins. Supplied in Tape & Reel (TR) and Cut Tape (CT) options, it suits both prototype builds and volume reflow assembly. The package is RoHS3 compliant with no exempt substances.
Active production with full compliance documentation
The part carries ROHS3 compliance, and TI provides the full datasheet, application notes, and IBIS models for signal-integrity simulation.
