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.

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.

(4)

For operation at elevated temperature, these devices must be derated based on a thermal resistance of

θja and Tj max, Tj = TA + θja PD.

(5)

The test circuit consists of the human body model of 100 pF in series with 1500

Ω.

Boldface numbers apply at temperature extremes. All other numbers apply at TA = 25°C, V

+ = 5V, C

osc = 0, and apply for the LMC7660

unless otherwise specified. Test circuit is shown in Figure 1 .

(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.
