Hello! It is a Friday, so it is #nakeddiefriday time again. Though with the massive influx of deprocessing images in the past week I was tempted to skip this one. ;-)

It is going to be a double one today; the first guest of this day is one M74LS14, made by Mitsubishi. It is a very classic hex inverter chip in low-power Schottky. The image may or may not be upside down. :-) Text identifying the die as LS14 is also present.

Many thanks to @root42 for supplying the sample!

The second exhibit of today is also an LS14, but manufactured by Signetics. The die features a characteristic star-shaped mark on the metal layer, along with product number 1807A.

Many thanks to @root42 for supplying the sample!

And that's all for today! I like the old chips for their simplicity, only one metal layer to work with. Figuring out the components is left as an exercise for the reader!

Until next time~
