It connects or isolates digital signal paths under a single enable control, with the switch passing signals rail-to-rail within the supply range. ## Supply and signal compatibility The supply voltage sets the signal swing — the switch passes analog or digital signals from ground to Vcc without adding propagation delay or distorting the waveform. Each of the eight channels handles a 1:1 connection, meaning one input maps to one output per channel. The independent circuit count of 1 means all eight switches share a common enable, so the entire bank toggles together. ## Package and board integration The 20-pin footprint matches the standard TSSOP-20 land pattern, and the low profile keeps the component clear of adjacent tall parts. The supply voltage source is single-supply, simplifying the power rail design — no split rails or negative supply needed. ## Compliance and sourcing The device is RoHS3 compliant, meeting the latest EU restriction directive for lead and other hazardous substances.","metaTitle":"SN74CB3Q3245PW Bus Switch, 8 x 1:1, 20-TSSOP, TI","metaDescription":"Texas Instruments SN74CB3Q3245PW bus switch, 8 x 1:1 circuit, 2.3-3.6V supply, 20-TSSOP.
