Absolute Maximum Ratings

Supply voltage range VCC –0.5 to 7.0 V Input / Output voltage VIN, VOUT –0.5 to VCC +0.5 V Input / Output diode current IIK, IOK ±Output current IOUT ±VCC, GND current ICC or IGND ±Power dissipation PTStorage temperature Tstg –65 to +150 °C Note: 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.

Recommended Operating Conditions

Supply voltage VCC 4.5 to 5.5 V Input / Output voltage VIN, VOUT 0 to VCC Operating temperature Ta –40 to 85 °Input rise / fall time tr, tf 0 to 500 ns VCC = 4.5 V Notes: 1. This item guarantees maximum limit when one input switches. Waveform: Refer to test circuit of switching characteristics.
