EEPROM-Programmable, Hex/Quad,
Power-Supply Sequencers/Supervisors
_______________________________________________________________________________________ 5
Note 1: Specifications guaranteed for the stated global conditions. The device also meets the parameters specified when 0 < V
IN1
< +6.5V, and at least one of V
IN3
through V
IN6
is between +2.7V and +5.5V, while the remaining V
IN3
through V
IN6
are
between 0 and +5.5V.
Note 2: Device may be supplied from any one of IN_, except IN2.
Note 3: The internal supply voltage, measured at ABP, equals the maximum of IN3–IN6 if V
IN1
= 0, or equals +5.4V if V
IN1
>
+6.5V. For +4V < V
IN1
< +6.5V and V
IN3
through V
IN6
> +2.7V, the input that powers the device cannot be determined.
Note 4: 100% production tested at T
A
= +25°C and T
A
= +85°C. Specifications at T
A
= -40°C are guaranteed by design.
Note 5: C
BUS
= total capacitance of one bus line in pF. Rise and fall times are measured between 0.1 x V
BUS
and 0.9 x V
BUS
.
Note 6: Input filters on SDA, SCL, A0, and A1 suppress noise spikes < 50ns.
Note 7: An additional cycle is required when writing to configuration memory for the first time.
