[time-nuts] ECL Discussion: The On Semi MC100LVEL34 (/2/4/8 Prescaler/Divider)

[Alex Pummer]

Hello Mr. Westmoreland

Yes we know that part and used in the past in many application in the 
previous  incarnation  from Motorola. Interestingly the older 5V parts 
were faster see the old Motorola datasheet, also for some reason the AZM 
parts were also faster,
any goo explanation for that?
