Modifications:
• 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.
• Section 6.1 “Enable”: added new 3
rd
paragraph
• Figure 5 “Typical application: multiple expandable 5-channel I
2
C-bus hubs”: added 2
nd
paragraph
below drawing.
• Figure 6 “Bus waveforms”:
– changed symbol from “t
st
” to “t
stretch
”
– changed symbol from “t
r1
” to “t
PHL1
”
– changed symbol from “t
r2
” to “t
PHL2
”
– changed symbol from “t
Er1
” to “t
PLH2
, t
PLH1
”
• Table 3 “Limiting values”:
– changed symbol/parameter from “V
CC
to GND, supply voltage range V
CC
” to
“V
CC
, supply voltage” (and placed “V
CC
to GND” in Conditions column)
– changed symbol/parameter from “V
bus
, voltage range I
2
C-bus, SCL or SDA” to
“V
I2C-bus
,I
2
C-bus voltage” (and placed “SCL or SDA” in Conditions column)
– changed symbol/parameter from “I, DC current (any pin)” to “I
I
, input current” (and placed
“any pin” in Conditions column)
– changed parameter for P
tot
from “power dissipation” to “total power dissipation”
• Table 4 “Static characteristics”:
– sub-section “Supplies”; symbol I
CCH
: changed parameter from “quiescent supply current, both
channels HIGH” to “HIGH-level supply current”; moved “both channels HIGH” to Conditions
column
– sub-section “Supplies”; symbol I
CCL
: changed parameter from “quiescent supply current, both
channels LOW” to “LOW-level supply current”; moved “both channels LOW” to Conditions
column
– sub-section “Supplies”; symbol I
CCLc
: changed parameter from “quiescent supply current in
contention” to “contention LOW-level supply current”
– sub-section “Input SCL; input/output SDA”, symbol used for parameter “input leakage current”
changed from “I
I
” to “I
LI
”
– sub-section “Input SCL; input/output SDA”, symbol V
OL
−V
ILc
: parameter changed from “LOW
level input voltage below output LOW level voltage” to “difference between LOW-level output
and LOW-level input voltage contention”
– (old) table note 1 is split into (new) Table note [1] and Table note [2]
