Each of the ten switches passes a digital signal with low on-resistance when enabled, and presents a high-impedance disconnect when disabled — useful for hot-swap bus isolation, memory bank switching, or sharing a peripheral bus between two controllers. The part operates from a 2.3 V to 3.6 V supply. The industrial temperature range (-40°C to 85°C) suits it for outdoor telecom cabinets, factory-floor controllers, and automotive infotainment (non-safety) modules. Packaged in a 24-TSSOP (4.40 mm width), it fits dense PCB layouts where board area is constrained. The surface-mount footprint matches standard pick-and-place assembly. ## What the 10 x 1:1 circuit means for your BOM Ten independent 1:1 switches means each channel is a single-pole single-throw (SPST) pass gate — one input, one output, no muxing. If your design needs to isolate ten data lines, this single IC replaces ten discrete FET switches or a larger bus-switch array. The single-supply rail simplifies power routing compared to dual-supply analog switches. Because the part is a bus switch (not a buffer or level translator), the output follows the input with negligible propagation delay. This matters for timing-critical buses like SPI clock lines or parallel memory interfaces where added delay would violate setup/hold margins. ## Lifecycle and sourcing posture The SN74CB3Q6800PWR carries an Active product status and ROHS3 compliance.","metaTitle":"SN74CB3Q6800PWR Bus Switch, 10 x 1:1, 24-TSSOP","metaDescription":"TI SN74CB3Q6800PWR bus switch, 10 x 1:1 circuit, 2.3V–3.6V supply, -40°C to 85°C, 24-TSSOP.
