ST202EB datasheed: table 7 typo?

[Dan K.]

The ST202EB (ST202EC, ST232EB, ST202EB, ...) RS232 receiver's datasheets shows the following application circuit.

Table 7 lists recommended capacitors values for C2-C5 (for the device ST202E is states 0.1 nF, for device ST232 it states 1uF).

I think this is a typo.

It should rather read C1-C4, as these capacitors are associated directly with the voltage doubler and voltage inverter stages of the tranceiver IC. I believe that C5 is rather a simple bypass/decoupling capacitor.

What do you think?

Best regards,

Dan

Hello Dan,

Thank you for your notice.

Mentioned table states 1uf for ST232E and 0,1uF for ST202E which is correct.

But you are right for capacitors designators. C5 is just decoupling capacitor and table should mention C1 to C4

Best regards
