Modifications: (continued)
– deleted (old) Figure 3, “Pin configuration for DIP16”
– pin names changed from “AD0, AD1, AD2” to “A0, A1, A2”, respectively
Section 6.2 “Pin description”: (old) Table 3, “Pin description for SO16, TSSOP16” and (old)
Table 4, “Pin description for SSOP20” are merged in (new) Table 3 “Pin description”
Section 7.1 “Device address” re-written
Section 7.1.1 “Address maps” re-written
Section 8.1 “Quasi-bidirectional I/Os” re-written
“trst(INT)”
– timing measurement symbol corrected from “tv(D)” to “tv(INT)”
– timing measurement symbol corrected from “td(rst)” to “trst(INT)”
Section 8.4 “Power-on reset”: second and third sentences re-written
Figure 9 “Read mode (input)” modified: corrected label from “data into port” to “data at port”
Section 8.5 “Interrupt output (INT)”, fourth, fifth and sixth paragraphs re-written; added new
seventh paragraph
(changed from “device 8, PCA8574” to “device 16, PCA8574A”)
– 1st sentence changed from “maximum sinking current of 25 mA per bit”
to “minimum guaranteed sinking current of 25 mA per bit at 4.5 V”
– 4th sentence changed from “device total limit” to “device recommended total limit”
Figure 16 “High current-drive load application” modified: added resistor on P6 and P7 signal
lines
Added (new) Section 10.4 “Migration path”
characteristics
Table 10 “Dynamic characteristics”, sub-section “Interrupt timing”:
– symbol/parameter corrected from “tv(D), data input valid time”
to “tv(INT), valid time on pin INT”
– symbol/parameter corrected from “td(rst), reset delay time”
to “trst(INT), reset time on pin INT”
Deleted (old) Figure 18, “Package outline SOT38-1 (DIP16)”
