The format of this data sheet has been redesigned to comply with the new identity guidelines of
NXP Semiconductors.
Legal texts have been adapted to the new company name where appropriate.
Figure 11 “Write to register” : changed symbol from “t pv ” to “t v(Q) ”
Figure 13 “Read input por t register” :
– changed symbol from “t ph ” to “t h(D) ”
– changed symbol from “t ps ” to “t su(D) ”
Table 11 “Programming PCA9533” , 6 th table body row: changed from “Set prescaler PWM1 to dim
at maximum frequency” to “Set prescaler PSC1 to dim at maximum frequency”
Table 12 “Limiting values” : changed symbol/parameter from “I I/O , DC output current on an I/O”
to “I O(LEDn) , output current on pin LEDn”
Table 13 “Static characteristics” :
– descriptive line below table title: phrase “TYP at 3.3 V and 25 ° C” is re-written as Table note [1] ,
with reference to it at column heading “Typ”
– sub-section “I/Os”: symbol for parameter “input leakage current” changed from “I L ” to “I LI ”
Table 14 “Dynamic characteristics” :
– symbols t VD;DAT (L) and t VD;DAT (H) are merged as “t VD;DAT ”; LOW and HIGH levels noted under
Conditions
– symbol/parameter changed from “t PV , Output data valid” to “t v(Q) , data output valid time”
– symbol/parameter changed from “t PS , Input data setup time” to “t su(D) , data input set-up time”
– symbol/parameter changed from “t PH , Input data hold time” to “t h(D) , data input hold time”
Added soldering information
Added Section 16 “Abbreviations”
