All parameters are guaranteed over the virtual junction temperature range by design. Pre-testing is performed at T
temperature on wafer level. Cased products are tested at T
test conditions to cover the specified temperature and power supply voltage range.
Duty cycle clock should be as close as possible to 50 %.
