It's correct. TI, et al. don't give sufficient detail for us to understand why.Is the reference here to 'positive' on Cext (pin 10) correct?
Since pin 11 connects via Rint or via the external timing resistor to Vcc, then surely the positive terminal of the external cap should be on pin 11, not 10? This would be important if the cap were an electrolytic one.
I haven't seen a datasheet from any manufacturer that gave enough detail. I think Fairchild Semi had an application note (AN-366?) that said using resistors larger than the recommended range could cause permanent damage. I tried with the 560k that was used in that thread. It didn't work and, luckily, didn't seem to damage the part.As you say, TI et al are certainly mean with detail.
