The SN74LVC1G57 and the NC7SZ57 have identical behaviour. Neither one can implement a true OR gate. You find the OR gate in the NC7SZ57 datasheet because that datasheet is shared between the NC7SZ5 7 and the NC7SZ5 8 . For an OR gate, use the SN74LVC1G58…
Hello Benson,
I don't see any questions in your post. What would you like to know?
Are you confused about what a Schmitt-trigger input is?
If so, here's an app note about Schmitt-trigger inputs: www.ti.com/.../scea046.pdf
Do you need a Schmitt…

Hi Muthukumar,
The CD54HC4046A contains a VCO to produce a phase-locked square wave to match your incoming signals. If you don't need this functionality, you can just use an XOR gate to get the frequency match, then filter the output to get an analog…
Thank you , Clemens for your contribution .
Kuo ,
I am not qualified to comment on the NXPs part , however,the NXP has schmitt trigger action on the inputs according to the datasheet which is not the same as schmitt trigger inputs . The input transition…
Part Number: SN74LVC1G97 Other Parts Discussed in Thread: SN74LVC1G57 , TINA-TI Has anyone sucessfully used the SN74LVC1G97 (or 1G57) as a gated oscillator? Asking as I can't simulate it due to the lack of a Spice model for TINA.
Just 2 Hz is the goal…
