Original question:

SN74LVC8T245: Channel-to-Channel Skew

SN74LVC8T245: channel-to-channel and part-to-part skew

Shubham Pandey

Part Number: SN74LVC8T245
Other Parts Discussed in Thread: SN74LVCH8T245, SN74LXC8T245

I would like to know channel to channel skew of SN74LVC8T245 / SN74LVCH8T245, when I and driving VccA=3.3V and VccB = 5V with CL= 15pF.

Also please let me know the part-to-part skew for the part under similar conditions.

Can you please refer me some document where I can get this data or similar data for LVC logic family translators.

    Hey Shubham,

    The best place to find this data is in the data sheet. If it isn't in there, that means it wasn't characterized for the device. I recommend using the newer SN74LXC8T245 device which is p2p and provides output skew in Section 6.12 of the data sheet. Worst case part to part skew is going to be the difference between Tpd max and Tpd min. If the devices are from the same Lot and are at the same temp and voltage, then its likely only going to be a few ns.
