Initial V

turn-on minimum remains as 2.2 V but the 3 V to 30 V specifications apply afterward.

is a digital signal.

V
4MON
threshold limits (see Table 6) are designed to primarily allow V
4MON
to monitor low voltage inputs. The V
4MON
input pin is capable of withstanding voltages up to
30 V. One application where this 30 V capability is useful is electronic media-oriented systems transport (eMOST) diagnostic circuits.
5
The
RESET
short-circuit current is the maximum pull-up current when
RESET
is driven low by a microprocessor bidirectional reset pin.
6
It is typical for the SCL and SDA to have resistors pulled up to V
3MON
. However, care must be taken to ensure that the minimum V
IH
is met when the SCL and SDA are
driven directly from a low voltage logic controller without pull-up resistors.
