Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specified.
Note 3: Maximum capacitive load, C
B
, for SCL and SDA is 400pF. Data and
clock rise time (t
r
) and fall time (t
f
) are:
(20 + 0.1 • C
B
)(ns) < t
r
< 300ns, and
(20 + 0.1 • C
B
)(ns) < t
f
< 300ns
C
B
= capacitance of one bus line in pF. SCL and SDA external pull-up
voltage, V
IO
, is 3V < V
IO
< 5.5V.
elecTrical characTerisTics
The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 25°C and V1 = 12V. (Note 2)
Note 4: Guaranteed by design, not directly tested.
Note 5: EEPROM endurance and retention are guaranteed by design,
characterization and correlation with statistical process controls. The
minimum retention specification applies for devices whose EEPROM has
been cycled less than the minimum endurance specification.
Note 6: EEPROM endurance and retention will be degraded when T
J
> 85°C.
