TS3A27518E: TS3A27518ETRTWRQ1 delay time

maayan hasson

Part Number: TS3A27518E

Tool/software:

We are using TS3A27518ETRTWRQ1, and we don't understand from the datasheets what is the delay time of the mux.

the off and on time is different from what we are looking for, because it is indicated the 90% of the out signal and not 50% as usual. We need the propagation time between the change in the input voltage to the corresponding change in the output voltage

thank you

A closed switch behaves like a resistor, so the propagation delay can be very short (much less than 1 ns), depending on how you measure. But the switch has a resistance and capacitance, so it will distort signals in some way. The exact behaviour depends strongly on the driving and loading conditions, so it does not make much sense to specify a propagation delay for test conditions that are not realistic for most applications. See [FAQ] How do I Approximate Propagation Delay and Channel to Channel Skew in an Analog Switch/Multiplexer?
