I am using LIN Protocol for Parking Brake functionality. baud rate : 10.4Kbps

1) I am sending the go to sleep command in $3C frame, after 50ms sending 0v to NSLP to put LIN Transceiver into sleep Mode but it is taking 9s for INHIBIT pin to go low from the trigger of $3C Frame. My understanding is once the NSLP goes to Zero, immediately INH Should go to low.

1) Is this the correct behaviour?
2) if some presses the Button (LIN Slave) during the 9s how the behaviour will be ?
3) Will LIN Slave send the wakeup pattern?
4) how INH pin will behave since it is already high?

When you are speaking about LIN transciever chip, you must specify its partnumber. For example, I suggest that you are using NXP's TJA1020 http://www.nxp.com/documents/data_sheet/TJA1020.pdf

It have INH output pin with two states: active high, when chip in non-sleep mode, and high-impedance (Z-state), when chip in sleep mode.

Also, I suggest that there is no load on INH pin.

So, when you turn on sleep mode, INH discarged only through your multimeter (scope?), and it takes few seconds.
