ELECTRICAL CHARACTERISTICS
Minimum and maximum parameters are characterized over the operating temperature range unless otherwise noted, but may
not be production tested at that temperature. Production test limits with statistical guardbands are used to ensure high
temperature performance. ⁽¹⁾

(1) Source currents (out of the device) are negative while sink currents (into the device) are positive.
(2) The typical values indicated in this table are the expected values during operation under normal operating conditions: nominal V_CC,
V_CCIO, or V_CCAD, room temperature.
(3) This does not apply to the PORRST pin. For PORRST exceptions, see the RST and PORRST Timings section.
(4) These values help to determine the external RC network circuit. For more details, see the TMS470R1x System Module Reference Guide
(literature number SPNU189).
(5) V_OL and V_OH are linear with respect to the amount of load current (I_OL/I_OH) applied.
(6) Parameter does not apply to input-only or output-only pins.
(7) Some of the 2 mA buffers on this device are zero-dominant buffers, as indicated by a -z in the Output Current column of the Terminal
Functions table. If two of these buffers are shorted together and one is outputting a low level and the other is outputting a high level, the
resulting value will always be low.
