Help Epprom identification

[Hornnumb2]

I search these chip numbers but had no luck, can somebody tell me which is the epprom. Thanks

Include the package in your search terms.

Google "15532 SOP-8">"BA15532F"=low noise op amp.

"7421 SOP-8"> probably ISO7421EDR "digital isolator" or IRF7421 mosfet+ diode.

I struggled to quickly get concrete data on the third one, but it probably isn't an EEPROM with 4 pins tied together, perhaps a mosfet or some power supply chip.

Last one I'm not sure on, can't quite read the first few characters, but again, probably not a serial EEPROM with two pins tied together.

The last one should be an I2C EEPROM produced by Microchip.

Thanks that last ones numbers are terrible...
