Storage Temperature (T STG ) −65˚C to +150˚C Maximum Junction Temperature (TJ) Ceramic +175˚C VEE Pin Potential to Ground Pin −7.0V to +0.5V Input Voltage (DC) V EE to +0.5V Output Current (DC Output HIGH) −50 mA ESD (Note 3) ≥2000V Recommended Operating Conditions Case Temperature (TC ) Military −55˚C to +125˚C Supply Voltage (VEE ) −5.7V to −4.2V Note 2:Absolute maximum ratings are those values beyond which the de- vice may be damaged or have its useful life impaired. Functional operation under these conditions is not implied.

This provides “cold start” specs which can be considered a worst case condition at cold temperatures. Note 5:Screen tested 100% on each device at −55˚C, +25˚C, and +125˚C, Subgroups 1, 2, 3, 7, and 8. Note 6:Sample tested (Method 5005, Table I) on each manufactured lot at −55˚C, +25˚C, and +125˚C, Subgroups A1, 2, 3, 7, and 8. Note 7:Guaranteed by applying specified input condition and testing VOH /VOL .
