with a slightly higher value. When this Ôbuffered lowÕ is applied to another PCA9515, PCA9516A, or PCA9518A in series, the second PCA9515, PCA9516A, or PCA9518A will not recognize it as a Ôregular lowÕ and will not propagate it as a Ôbuffered lowÕ again. The PCA9510A/9511A/9513A/9514A and PCA9512A cannot be used in series with the PCA9515, PCA9516A, or PCA9518A but can be used in series with themselves since they use shifting instead of static offsets to avoid lock-up conditions. The PCA9515 SCLn/SDAn C is aboit 200 pF versus the normal < 10 pF when V CC

Similar to the PCA9516 but with four extra open drain signal pins that allow the internal device Hub 2 PCA Hub 3 logic to be interconnected into an unlimited number of segments with

The 2 Sx/Sy side is only intended for, and compatible with, the normal I C-bus logic voltage levels of I C-bus master and slave chips, or even Tx/Rx signals of a second P82B96 if required. The Tx

The A-side of two or more PCA9517s can be connected together, however, to allow a star topography with the A-side on the common bus, and the A-side can be connected directly to any other buffer with

@ Dietmar Sch. wenn ich das richtig sehe erweitert der PCA9518 nur den I2C Bus, sprich mehr als 256 Geräte am Bus möglich, oder? Das hilft mir hier ja nicht weiter, mir geht es ja darum 1x I2C, 1xSPI und 1xRS232 zu haben. Oder hab ich da was falsch verstanden
vielfältig einsetzbar I²C? Ich benutze die Hardware des PIC, und möchte mit 400kHz einen I²C - Hub (PCA9518DWR) ansteuern. Dies wegen der unterschiedlichen Geschwindigkeiten der einzelnen Abgänge. Welche Geräte hängen am I²C? Beleuchtungsobjekte(100kHz und weniger), RTC (DS1307)(100kHz), Licht-& Temperatursensor
