Each switch presents a low on-resistance between the A and B ports when the corresponding output-enable (OE) pin is driven low, allowing digital signals to pass with minimal propagation delay — typically under 250 ps. ## Supply and signal integrity With four independent switches sharing a single 5 V supply, the SN74CBT3126D can multiplex or isolate four separate digital signals — for example, routing SPI chip-select lines or JTAG debug signals between a processor and multiple peripherals without adding series resistance. The part is ROHS3 compliant, and the standard 74CBT logic family has broad second-source availability if a BOM hedge is needed.","metaTitle":"SN74CBT3126D Bus Switch, 4 Circuits, 14-SOIC, TI","metaDescription":"Texas Instruments SN74CBT3126D quad bus switch, 4.5V-5.5V single supply, 14-SOIC surface mount.
