Electrical Characteristics
Specifications in standard type face are for T
Range ( T
the two operating ranges will be identified in the Temp Range column as Q0 for T
to +125°C. If no temperature range is indicated then the specification holds for both Q1 and Q0. Minimum and Maximum limits are
guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T
and are provided for reference purposes only. Unless otherwise stated the following condition applies: V
