Mouser has them - https://au.mouser.com/c/?q=SN74LS06N
What's the reason for the HEF4511? Are you driving a 7 segment LED?
Rather than using Mouser, Digikey, Element14, RS Components, XON and alike, Ewan or someone may have some of these ICs available.
Note: SN= prefix for TI, CD= prefix for NATSEMI/TI, HEF = prefix for PHILIPS/NXP
