How can I find this component?

I assume as a symbol?

PS: even untrained users should be able to convert another 10-20 pin component to this 14 pin component in the symbol editor within 15-20 minutes :wink:

If it would be there, then as CD4541 in the CD4000 library.
With or without . This means ‘bufferd’, but so far I know there are nomore unbuffered deviced on the market( but the CD4049).
MC1xxx says it was once from Motorola.

If this is your first time and doing it yourself won’t work, just ask.
