Note 1:
Absolute Maximum ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions. See Note 4 for conditions.
Note 2:
Connecting any input terminal to voltages greater than V
+
or less than ground may cause destructive latchup. It is recommended that no inputs from sources
operating from external supplies be applied prior to “power-up” of the LMC7660.
Note 3:
For operation at elevated temperature, these devices must be derated based on a thermal resistance of

= 0, and apply for the LMC7660 unless otherwise
specified. Test circuit is shown in Figure 1 .
Note 5:
Limits at room temperature are guaranteed and 100% production tested. Limits in
boldface
are guaranteed over the operating temperature range (but not
100% tested), and are not used to calculate outgoing quality levels.
Note 6:
The LMC7660 can operate without an external diode over the full temperature and voltage range. The LMC7660 can also be used with the external diode
Dx, when replacing previous 7660 designs.
Note 7:
The test circuit consists of the human body model of 100 pF in series with 1500
