Dear E2E,
Do we have p2p with TS3A44159, but lower C_NC/NO (ON/OFF)?

Jason,
The way to answer your question is to use the ti.com switch search tool. In order for a switch to be p2p it will need to have that same configuration and channel count.
The search tool below is filtered on configuration 2:1 and 4-channles. Next you can sort these 9 devices by on-state capacitance from least to greatest.
The next step is to look at the datasheets of the devices with lower on-state capacitance than the TS3A44159 and compare the pinouts. Be aware there are different names different types of pins:
power supply pins V+, Vdd, Vcc, Vss
control logic pins EN, IN, SEL, OE,
signal path COM, NO, NC, S, D
Comparing the pinouts of the lower capacitance SN74CB3T3257, TMUX1574, SN74CB3Q3257, TS3A5018, SN74CBT3257C, you can conclude that there is not a pin compatible solution for the TS3A44159.
You may notice on the table there is an inverse relationship between the on-state capacitance and on-state resistance.
What is driving the need for a lower capacitance device?
