SNOSBZ9C –APRIL 1997–REVISED APRIL 2013 www.ti.com
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 (1) under Electrical Characteristics for conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) 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.

(2) Limits at room temperature are specified and 100% production tested. Limits in boldface are specified over the operating temperature
range (but not 100% tested), and are not used to calculate outgoing quality levels.
(3) 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.
