Modifications:
Table 1 “Ordering information”: Topside mark for PCA9674APW is corrected
from “PA9674A” to “9674A”
Figure 1 “Block diagram of PCA9674; PCA9674A” modified: swapped positions of blocks
“INTERRUPT LOGIC” and “LP FILTER”
and (P0 to P7) signals
Combined (old) Table 3, “Pin description for SO16, TSSOP16” and Table 4, “Pin
description for HVQFN16” into one table: Table 3 “Pin description”
first paragraph is re-written
last paragraph: inserted phrase “or the newer PCA8574 or PCA8574A”
Section 7.1.1 “Address maps”: added (new) first paragraph
Table 4 “PCA9674 address map” modified: added separate columns for Read and Write
addresses and column for 7-bit hexadecimal address
Table 5 “PCA9674A address map” modified: added separate columns for Read and Write
addresses and column for 7-bit hexadecimal address
