*Pb-free PDIPs can be used for through hole wave solder processing

only. They are not intended for use in Reflow solder processing

applications.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTE:

1.

JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

Electrical Specifications

Test Conditions: VCC = 4.5V to 5.5V; Unless Otherwise Specified.

Typicals are at VCC = 5V, TA = 25°C, (Note 2)
