I found that BF60X datasheet doesn't contain information about General-Purpose Port Signal Output Delay. See screenshot below.
BF51X datasheet contains information on it.
I've measured that toggle operation ("0" > "1" > "0") in BF60X requires approximately 260 ns while BF51X toggle requires 20 ns.
Could 20 ns toggle time be achieved in BF60X? Where could I find information on it? GPO toggle time is very important in my application (relay protection system).
Thank you in advance.
