NAND GATE, AND GATE recommendation request

Hi, TI expert.

In order to prevent the pulse gate signal from appearing high at the same time in the customer, we want to configure the logic as follows.

I have a GATE device inquiry regarding that.

-----------------------------------------------

- NAND GATE (2CH) : ?
- AND GATE (4CH) : ?
- Vcc: 3.3~5V
- Propagation Delay: 10ns or less

-----------------------------------------------

Please recommend suitable NAND Gate and AND Gate.

Thank you.

    NAND: SN74LVC2G00
    AND: SN74AHC08 (The AHC propagation delay at 3.3 V is marginal. If this is important, use 2× SN74LVC2G08.)

    This logic function (AND with one inverted input) could be implemented with just the SN74LVC1G97, but would require four single-gate chips.
