Other Parts Discussed in Thread: SN74AHC14
Hello support team,
My customer ask if SN74HCS14 can accept 5.5V input voltage when VCC5V. Could you support?
Datasheet "Absolute Maximum Ratings" has notice (2), this looks like to allow Vi > VCC if the current keep less than 20mA. But, "Recommended Operating Conditions " shows Vi range is up to VCC, this looks like not to allow Vi >Vcc....
SN74AHC14 also has same notice (2) on "Absolute Maximum Ratings", but, Vi range is up to 5.5V, not VCC, this looks like to allow Vi >VCC (of cause, if less than 20mA
Thanks,
Koji Ikeda
