ABSOLUTE MAXIMUM RATINGS*

DC Supply Voltage (VDD) ........................................ +6.0V

Input Voltage, All Inputs (VIN) ............ – 0.3V to VDD +0.3V

Operating Temperature Range (TA) ............. 0°C to +70°C

Storage Temperature Range (TSTG) ..... – 65°C to +150°C

Lead Temperature (Soldering, 10 sec) (TSDR) ...... +300°C

* Static-sensitive device. Unused devices must be stored in conductive

material. Protect devices from static discharge and static fields. Stresses

above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. These are stress ratings only and functional

operation of the device at these or any other conditions above those

indicated in the Operational Specifications is not implied. Any exposure to

Absolute Maximum Rating Conditions may affect device reliability.

ELECTRICAL CHARACTERISTICS: VDD = 5V, fosc = 1 MHz, TA = +25°C, unless otherwise specified.
