(Unintentional) Comedy in data sheets
AndyC_772:
Just spotted this buried in the reference manual for an STM32 microcontroller:
"It must be used only if the product supply voltage is below 2.5 V. Setting this bit when VDD is higher than 2.5 V might be destructive"
I couldn't help but chuckle. Anyone else spotted anything in a data sheet that was meant to be funny, or wasn't meant to be but was anyway?
Yansi:
I do not see anything funny about it.
Better tell us which datahseet and where have you seen it.

Face colour is what now?? ???
penfold:
In the LM339 datasheet, page 14 near the bottom...

If a negative supply is not being used, do not place a capacitor between the GND pin of the device and system ground.

It's the only time I've seen such a recommendation, made me chuckle to think of the number of support requests of "your comparator is rubbish, it only works for a millisecond after I switch it on, then nothing" before they decided to update the datasheet.
