TS555 pin layout
« on: September 24, 2021, 05:57:24 pm »
Hi,

I'm trying to solder a TS555IDTTR timer IC into my pcb, but there is no apparent marking on the package to denote pin 1. How to resolve this ambiguity, how to determine the correct orientation of the chip? Thanks!

Welcome to the forum.

If SOIC packages don't have an specific pin 1 marker then they have a chamfer on the side of the package with pins 1-4 (Edit: in this case).
