FW: SN74AVC24T245ZRGR Need Prop delay. hotsales team,
Can you please help me verify prop delay for SN74AVC24T245ZRGR. Two quesitons. customer is in layout now.
1. I want to make sure that all 24 bits have the same prop delay through the chip. (Vcca = 1.8V, Vccb=3.3V, prop delay is 0.5 to 3.3ns).
2. what is the lane to lane prop delay deviation?

(Vcca = 1.8V, Vccb=3.3V, prop delay is 0.5 to 3.3ns). But what is the lane to lane prop delay deviation? Your timing is perfect I was just about to put this part into the schematics.

What voltage are you using to power the chip? page 9 of data sheet has (INPUT) (OUTPUT) Are you wanting to make sure all 24 bit have same prop delay through the chip and the time for this? laurie Verboort ________________________________

Our guarantee for skew for CMOS parts is 1ns into equal loads and they will usually run less than 500ps although not guaranteed.
Worst case skew is 200ps for the SN74AVC**T245 from the char data.
