The two independent switches share a common supply rail but are otherwise isolated — each channel can be controlled separately to gate a digital signal path on or off without loading the bus when disabled. ## 8-TSSOP footprint and board integration Housed in an 8-TSSOP package (4.40 mm width, 0.65 mm pitch), the SN74CBT3305CPW mounts on the board surface and occupies a compact footprint suitable for dense digital boards. The 8-TSSOP supplier device package matches the standard JEDEC MO-153 variation, so the land pattern is widely supported in PCB layout tools. The 0.65 mm lead pitch is fine enough to require careful solder-paste stencil design but is well within the capability of standard SMT assembly lines. No exposed thermal pad — the package relies on the leads for heat dissipation, so keep the trace widths adequate for the modest current levels (sub-100 mA typical for bus switching). The wide range means the switch's on-resistance and propagation delay will shift across temperature, but the datasheet's typical curves (not reproduced here) show the variation is within the logic-family noise margins for 5V CMOS.","metaTitle":"SN74CBT3305CPW Bus Switch, 2-circuit, 8-TSSOP, Active","metaDescription":"SN74CBT3305CPW bus switch, 2 independent 1:1 circuits, 4.5V-5.5V supply, -40 to 85°C, 8-TSSOP.
