SN74ALS139D Dual 2-Line to 4-Line Decoders/Demultiplexers
Semiconductors > Digital Logic > Decoders/Encoders/Multiplexers > Decoders > SN74ALS139 ACTIVE

so
Mehmet did not take the time to check if it was available (from the most common source of TTL) AND did not check the datasheets to see if other 139s were pin compatible and still got 15 responses.

Maybe Mehmet need see an optician. or someone else since he is in a hurry and the thread is still alive 5 hours after he posted.
