The 0.65 mm pin pitch is forgiving under a hot-air station — the leads are visible and accessible, so aligning a replacement part is straightforward. Pin 1 is marked with a dot on the top surface; the orientation notch on the package end confirms it before the part seats. ## Four independent switches on a single supply rail Each switch is a pass-gate with its own enable; when the enable is low the channel is off (high-impedance), and when high it connects the A port to the B port with minimal propagation delay. The 5 V supply range covers standard 5 V TTL and CMOS logic levels without a level translator.","metaTitle":"SN74CBT3126PWR Bus Switch, 4 Circuits, 14-TSSOP","metaDescription":"Texas Instruments SN74CBT3126PWR bus switch, 4 independent 1:1 circuits, 4.5-5.5V supply, -40 to 85°C, 14-TSSOP.
