(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Section 6.2 is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to V
SS
, unless otherwise noted.
(3) Continuous clamp current per pin is ±2 mA. This includes the analog inputs which have an internal clamping circuit that clamps the
voltage to a diode drop above V
DDA2
or below V
SSA2
.
(4) Long-term high-temperature storage and/or extended use at maximum temperature conditions may result in a reduction of overall device
life. For additional information, see IC Package Thermal Metrics Application Report (literature number SPRA953) and Reliability Data for
TMS320LF24xx and TMS320F28xx Devices Application Report (literature number SPRA963).
