Electrical and Thermal Characteristics
This section provides both AC and DC electrical specifications and thermal characteristics for the 750.
DC Electrical Characteristics
The tables in this section describe the DC electrical characteristics of the 750. The following table provides
the absolute maximum ratings.

Note:
1. Functional and tested operating conditions are given in Table ”Recommended Operating Conditions,” below. Absolute maximum ratings are stress rat-
ings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent
damage to the device.
2.
Caution:
V
must not exceed OV
by more than 0.3V at any time, including during power-on reset. This is a DC specification only. V

overshoot tran-
sients up to OV
