Electrical Characteristics
Unless otherwise noted, limits printed in
bold
characters are electrical testing limits at V
= 5.0V and T
= 25C. All other
limits are design goals for V

= 0C to 90C (refer to Application Note AN-336). This data sheet is still
preliminary and parameter limits are not indicative of characterization data with respect to power supply or temperature varia-
tions. Please contact your National Semiconductor Sales Office for the most current product information.
