Absolute Maximum Ratings
Item Symbol Ratings Unit Test Conditions
Supply voltage range VCC –0.5 to 7.0 V
Input voltage range *1 VI–0.5 to VCC + 0.5 V
Output voltage range *1, 2 VO–0.5 to VCC + 0.5 V Output : H or L
Input clamp current IIK ±20 mA VI < 0 or VI > VCC
Output clamp current IOK ±20 mA VO < 0 or VO >VCC
Continuous output current IO±25 mA VO = 0 to VCC
Continuous current through
VCC or GND ICC or IGND ±25 mA
Maximum power dissipation
at Ta = 25°C (in still air) *3 PT200 mW
Storage temperature Tstg –65 to 150 °C
Notes: The absolute maximum ratings are values, which must not individually be exceeded, and
furthermore, no two of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
