SN74LVC2G07: clock buffer

Stefan Lintner

Part Number: SN74LVC2G07
Other Parts Discussed in Thread: TXU0102, SN74LVC2G34

Hi Team,

can the SN74LVC2G07DRY be used to buffer two clock lines that are 5 V level and to convert them to 3.3 V as well?

What is the skew between the two devices? E.g., if one channel gives 2 ns delay, within which range can I expect the other channel to be?

Or would you recommend another solution for this, i.e: LMK1C110x

BR,
Stefan

Open-drain outputs have slow rising edges, depending on the value of the pull-up resistors.

Use an actual level shifter like the TXU0102, or a buffer with overvoltage-tolerant inputs like the SN74LVC2G34.

The typical skew is less than 1 ns. There is no guaranteed maximum.
