Hi guys.I am looking for the schematic diagram for the Siglent SDG 1025.Or, does anybody knows what kind of IC the U63 is? The letters on top does not give a hit on Google.Thanks in advance, Peter
HA14 and HC14 are both hex schmitt-trigger inverters. They have slightly different cmos characteristics, but function identically in most circuits. I’m guessing, due to this part’s proximity to the crystal, it functions as part of the 10Mhz time base oscillator. The other numbers on the chip are manufacturing and date codes, and will vary on a replacement part.What specific problem are you having that has you looking at this chip?
First find out what the package is: http://www.ti.com/pdfs/logic/qfncompare.pdfThen you know what you need to order:Part Marking PackageSN74AHC14DBR HA14 SSOP-14 SN74AHC14DGVR HA14 TVSOP-14 SN74AHC14PW HA14 TSSOP-14
