On-resistance is 35Ohm max. Channel-to-channel matching is 2Ohm max. Charge injection is 3pC. Crosstalk is -85dB at 1MHz.
There is no official second source listed, but the supply channel is stable for production BOMs. If you are freezing a BOM for a multi-year build, this part carries no near-term obsolescence risk.
Maximum turn-on time is 175ns, turn-off time is 145ns. Fast enough for audio multiplexing, relay replacement, and moderate-speed data acquisition front ends.
