SCLS318T March 1996 – January 2016 SN74AHC1G04
The SN74AHC1G04 device contains one inverter gate. The device performs the Boolean function Y = A.
This single gate inverter has Schmitt-Trigger action on its input, allowing for slower rise and fall times and some noise rejection. This is not a true Schmitt-Trigger, so there is a limit on rise and fall times.
