e2e,
I'm asking for the datasheet values for propagation delay and saying they are missing from the datasheet.
Thank you,
Adam

For analog switches, datasheet tpd values are often computed for an infinitely strong signal source, which is not realistic. So this missing specification is not a big loss.
Hello Adam,
I agree with Clemens and to find the propagation delay on this device use the FAQ attached to Clemens response.
In addition the propagation delay can be found using the following method using the FAQ and the values in the datasheet,
TS5A3157 at 3V supply with an RC load of RL = 50Ω and CL = 20pF. At 3V, the typical on resistance is 12Ω, While the on capacitance is 17.5pF. Now an typical operation point can be found. The loading capacitor is going to be 20pF + 17.5pF and the RTH is going to ~12 Ohms (typical) because RON << RL. This gives an approximate propagation delay of 450ps (typical) .
12ohm x37.5pf =450 ps typical
