12 Ohm on-resistance and 4 ns switching — signal-path fit
The TC7SB67CFU,LF(CT: The 4 ns turn-on and 4.5 ns turn-off times mean the switch can pass digital edges up to roughly 100 MHz before propagation delay distorts the waveform; the 5 pF channel capacitance limits off-state isolation to about -30 dB at that frequency. The 1 µA max leakage current is negligible for source impedances below 100 kΩ; won't shift the DC bias in a precision divider or a high-impedance sensor front-end.
Industrial temperature grade in a 5-pin SC-70 footprint
The 5-pin SC-70 / SOT-353 body measures 2.0 x 2.1 mm with 0.65 mm pitch; the footprint is shared with the TC7SB66CFU,LF(CT normally-closed variant, so a PCB can accommodate either with a BOM change only. Surface-mount assembly with Tape & Reel or Cut Tape packaging — the reel quantity is standard for the SC-70 family; the Cut Tape option suits prototype or low-volume builds without committing to a full reel.
