UCC2946-Q1: Reset time out period and watchdog time out period minimum and maximum values calculation

Part Number: UCC2946-Q1
Other Parts Discussed in Thread: SN65HVD75

I am planning to use the below part number in one of my application. I need technical data for this part. can you please support.

Part Number selected : 
1. UCC2946-Q1
2.SN65HVD75

Question on UCC2946-Q1:

1. The reset period is given for 64nF is 140msec to 320 msec. How this tolerance is calculated. I could able to calculate the typical value as 200mSec. How can I compute worst case tolerance for the reset and watchdog time out period? I can take capacitor tolerance, and able to calculate minimum and maximum values . Is there any tolerance to be considered in the IC apart from capacitor tolerance.?

TRP = 3.125 × CRP


2. I saw that this part number is released on 2004 and still it is active. will this part active for next 10 years?what is the longevity/product life cycle of this part?

2.SN65HVD75 : 

1. For receiver input VOH minimum given as 2.4V at 8mA. what is the VOH level for the current of 100uA,1mA,2mA?

 

Thanks
