1. Data measured with VEE = –5.2 ± .1V assuming a +50°C rise between ambient (ta) and junction temperature (TJ) for 0°C, +25°C, and +70°C. Specification
will vary based upon TJ. These conditions will be met with an ambient 70°C airflow of 200 LFM.
2. Typical limits are at 25°C, VCC = 5.0V.
3. These input levels provide zero noise immunity and should only be tested in a static, noise-free environment.
