HCS512
9.0 ELECTRICAL CHARACTERISTICS FOR HCS512
Absolute Maximum Ratings â
Ambient temperature under bias............................................................................................................. -55°C to +125°C
Storage temperature ............................................................................................................................... -65°C to +150°C
Voltage on any pin with respect to VSS (except VDD)......................................................................... -0.6V to VDD +0.6V
Voltage on VDD with respect to Vss................................................................................................................... 0 to +7.5V
Total power dissipation (Note 1) ........................................................................................................................... 800 mW
Maximum current out of VSS pin ........................................................................................................................... 150 mA
Maximum current into VDD pin .............................................................................................................................. 100 mA
Input clamp current, Iik (VI < 0 or VI > VDD) .........................................................................................................± 20 mA
Output clamp current, IOK (VO < 0 or VO >VDD) ..................................................................................................± 20 mA
Maximum output current sunk by any I/O pin.......................................................................................................... 25 mA
Maximum output current sourced by any I/O pin..................................................................................................... 20 mA
Note: Power dissipation is calculated as follows: Pdis = VDD x {IDD - â IOH} + â {(VDDâVOH) x IOH} + â(VOl x IOL)
â NOTICE: Stresses above those listed under âAbsolute Maximum Ratingsâ may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this speciï¬cation is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
