4.0 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 +6.5V

Voltage on RESET with respect to VSS ...................................................................................................... -0.3V to +14V

Voltage on all other pins with respect to VSS ................................................................................. –0.3V to (VDD + 0.3V)

Total Power Dissipation (1) ...................................................................................................................................800 mW

Max. Current out of VSS pin ..................................................................................................................................300 mA

Max. Current into VDD pin .....................................................................................................................................250 mA

Input Clamp Current, IIK (VI < 0 or VI > VDD) ................................................................................................................... ±20 mA

Output Clamp Current, IOK (V0 < 0 or V0 > VDD)............................................................................................................. ±20 mA

Max. Output Current sunk by any Output pin..........................................................................................................25 mA

Max. Output Current sourced by any Output pin.....................................................................................................25 mA

Note 1: Power Dissipation is calculated as follows: PDIS = VDD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOL x IOL)

†NOTICE: Stresses above those listed under “Maximum ratings” 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 operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods

may affect device reliability.

Note:

Voltage spikes below VSS at the RESET pin, inducing currents greater than 80 mA, may cause latch-up.

Thus, a series resistor of 50 - 100Ω should be used when applying a “low” level to the RESET pin rather

than pulling this pin directly to VSS. .
