laual Posted January 28, 2020 Report Posted January 28, 2020 (edited) Hi, First post, after buying some PCB and parts to begin the core of a mbseq 4+. Part IC1A is giving me a hard time in that I can't figure out the orientation of the part. All datasheets indicate a hole or a notch but all I've got on the part is a printed line. I'm guessing the printed line replaces the hole or the notch, but I would like some advice before I solder all pins of the 3 IC parts. Thanks, Laurent Edited February 25, 2020 by laual Quote
latigid on Posted January 28, 2020 Report Posted January 28, 2020 Hi Laurent, feel free to post a clear photo/part number and I can check for you. The line should go along pins 1-2-3-4 etc. so the text of the part is readable with the line along the bottom. Best; Andy Quote
laual Posted January 28, 2020 Author Report Posted January 28, 2020 Hi Andy, The Mouser part number is 595-SN74HCT125DR and the number on PCB is IC1A. Here is a link https://cloud.blackshell.be/s/LPPo9q8f5rr7mqE Laurent Quote
latigid on Posted January 28, 2020 Report Posted January 28, 2020 Hi Laurent, The part is correctly oriented as pictured, with the "vertical" bar closest to pins 1/16. Bon courage! Andy Quote
laual Posted January 28, 2020 Author Report Posted January 28, 2020 Hi again Andy, Thanks for the confirmation :) Merci! Laurent Quote
