Even for a short time 1A would likely damage the device.

A device that has lower capacitance would be TS5A9411 . It has 8.5pF which would be within your 30pF requirement.

The device would enter a unknown state, the status of the MUX would be High impedance or partially open meaning some signal could pass through. 0V would guarantee the device is not partially on or operational.

I would like to find out if it&#39;s possible to exceed the recommended value temporarily without damaging the part. Of course, the temporal mean would be below the maximum recommended value.

If the current does not exceed the recommended in the datasheet than it would be fine to connect to the pins.

The image below illustrates what I am tryinto do. The VSET/VID pin need to have less than 30pF capacitance. Basically less than 30pF on the COM pin to GND when the switch is connected COM to NC or COM to NO. The TS5A3157 specifies Cno(on)/Cnc(on) as 17.5pF (typ) and ccom(on) as 17.5pF typ. Does this mean that if the switch is on and COM is connected to NC the the capacitance seen at the com pin is 17.5pF + 17.5pF (35pf) or just 17.5pF? What is the maximum capacitance values? If TS5A3157 the is not suitable what part would you recommend?

These inputs require either appr. -30 V or 0 V, so I found wiring the TMUX6234 to -30 V and 3.3 V to be a suitable solution for controlling these switch inputs with 1.8-V-logic. However, switching time plays a crucial role in my application. Therefore, I would like to know more details about the pulse behaviour of the part, such as the maximum pulse current and whether it is safe to directly connect the outputs to the pins. Unfortunately, the chip manufacturer could not provide detailed information on the switching input pins, but I suspect it is in the order of a few pF. The desired switching time would be in the nanosecond-range. I look fordward to receiving some insights into pulse operation.

We noticed the PCN includes a wafer diameter change (200mm to 300mm), a die shrink, and a wire bond change from 0.96mil Au to 0.8mil Cu. While the updated datasheet (Rev. K) mentions changes in the electrical tables, we need to understand the exact delta between the Pre-PCN and Post-PCN devices to ensure system compatibility. Could you please clarify the following points regarding the new Die Rev A: Electrical Characteristics: Is there a comparison table for typical values (e.g., Ron, Cio_ON, Cio_OFF) between the old and new revisions? Propagation Delay &amp; Load Capacitance: How exactly will the propagation delay (RC time constant) be impacted by the new die and Cu wire bond? SDP Request: Could you share the Supporting Data Packet (SDP) for this specific PCN? Any detailed characterization data would be highly appreciated to help the customer&#39;s EE team approve this transition.

You can typically resolve this by improving their oscilloscope probing technique or adding series termination resistors near the driving source.
