D-flip-flop with Schmitt Trigger inputs

Genius 9485 points

Hello Team,

does TI provide a D-flip-flop (ideally pin compatible with  SN74AHCT74PWR) which has Schmitt-Trigger inputs or CLK, /PRE and /CLR, please?

Thanks,

Hans

  • We have some single bit devices with some hysteresis. They are not true schmitt triggers and will have a relaxed ris and fall limit.  they are also low voltage.

    These are all I could find

    SN74AUC74

  • In reply to Chris Cockrill:

    How about SN74AUP1G74 who's datasheet claims to have "Schmitt-Trigger Action"

  • In reply to Richard Woodham:

    This part will have a rise and fall limit of 200ns/V max. Not a true schmitt trigger.

  • In reply to Chris Cockrill:

    Hi Chris,

    What is the typical rise/fall time limit for a true schmitt trigger?

    Thanks.

  • In reply to ytan:

    A true schmitt trigger will not have a limit
