ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings †

Ambient temperature under bias.............................................................................................................-40°C to +125°C

Storage temperature ...............................................................................................................................-65°C to +150°C

Voltage on VDD with respect to VSS .......................................................................................................... -0.3V to +5.5V

Voltage on all other pins with respect to VSS (except VDD)............................................................. -0.6V to (VDD + 0.6V)

Total power dissipation (Note) .............................................................................................................................700 mW

Maximum current out of VSS pin ...........................................................................................................................150 mA

Maximum current into VDD pin ..............................................................................................................................125 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 output pin ....................................................................................................25 mA

Maximum output current sourced by any output pin ...............................................................................................25 mA

Note:

Power dissipation is calculated as follows:

PDIS = VDD x {IDD -

∑ IOH} + ∑ {(VDD - VOH) x IOH} + ∑(VOL x IOL)
