[MCL65+] SN74LVC573AN substitute? #12

Closed aleksander-martin closed 1 year ago

aleksander-martin commented 1 year ago

Can SN74LVC573AN be replaced by other series? On the schematics is written 74LS573, but I am not sure will it work?

MicroCoreLabs commented 1 year ago

The pinouts are different so they are not interchangeable. If you change the schematics and layout then you can use a '373.

Well, I didn't want to replace 573 with 373. I just want to replace LVC with LS (or any other). Pinout for all 573 is the same in all series :)

Ah I see.. Any logic family which has 5V tolerant inputs and 3.3V outputs will work fine.

HCT should work.
