Good day. I hope everything is fine.
Our customer want to use the SN54LS123-SP and they have a few question about it. Kindly refer to their question below.
1. Can the Cext be a ceramic capacitor? If yes, will a switching diode be required when using a ceramic capacitor for Cext?
2. Is there any tools available for calculating Cext and RT?
I would appreciate if you could help us with this inquiry. Thank you.
