Need help with ID-ing two 8 pin IC's
« on: June 05, 2017, 03:37:52 pm »
I would like some help with ID-ing these two components (inside red square).

On the left the "103" and on the right the "E01" (both ~ 1.5mm long). There both 8 pin. I tried (ofc) Google, but I'm not sure what it could be. Maybe a op-amp/comparator of some sort?

The 103 is connected via a flat cable to 2 momentary push switches (G, C an D). The Pins A, B, C and D are all getting 3.2V and G=Ground (0V).  C and D are connected via the push switch to G (ground). The pins below I couldn't probe.

The E01, I have no further info on. Does'n seem to be connected to the flat cable at all (nevertheless, would like to know the chip).

Thanks!

Resistor networks. They are both marked 103, but one is upside down. 1 or 10 kohm, depending on manufacturer numbering system. Probably just 4 resistors per pack for pullup/pulldown.

I would say they are 10k, E24 series (5% tolerance)

On the bottom left corner of your red rectangle, there is another10k0, but E96 series (1%).
