The 400 ohm on-resistance is moderate — fine for driving high-impedance loads like op-amp inputs or ADC front-ends, but not for power switching or low-impedance audio outputs where you'd want single-digit ohms. The 275 ns turn-on and 200 ns turn-off times are fast enough for scanning sensor arrays or multiplexing signals at moderate rates, though not for high-speed video or RF switching. Crosstalk is rated at -62 dB at 1 MHz, which gives decent channel isolation for audio-band or low-frequency analog multiplexing; at higher frequencies it degrades, so keep that in mind for mixed-signal designs with fast edges nearby. Leakage current is a maximum of 500 pA off-state, and charge injection is 2 pC — both low enough that they won't disturb precision analog measurements in most data-acquisition or sample-and-hold circuits. The 10 pF / 14 pF channel capacitance (source off / drain off) is modest; it adds a small RC time constant with the source impedance, but for signals below a few hundred kHz it's rarely a concern.
It comes in a 16-pin SOIC-8 body (0.154" wide, 3.90 mm width), surface-mount only. The '+' suffix on the order code indicates lead-free / ROHS3 compliant finish — no lead in the solder plating. It ships in a tube, not tape-and-reel, so if your pick-and-place line expects reels you'll need to transfer to tape or order the reel-pack variant.
It is ROHS3 compliant, so no restriction on use in new designs for RoHS-regulated markets.
