Packaged in 16-TSSOP (4.40 mm width), the 0.65 mm pin pitch routes cleanly on a two-layer board with standard trace widths. The surface-mount footprint is shared across many 74CBT logic devices, so a single PCB pad pattern can serve multiple BOM variants.","metaTitle":"SN74CBT3257PWR 4x2:1 Mux/Demux, 4.5-5.5V, 16-TSSOP","metaDescription":"Texas Instruments SN74CBT3257PWR 4 x 2:1 multiplexer/demultiplexer.
