Pulse-testing techniques maintain junction temperature close to ambient temperature (250-
s-wide pulse, less than 0.5% duty cycle); thermal
effects must be taken into account separately.
Specified by design, not tested in production.
§ Input currents do not include logic input currents (presented in electrical characteristics for logic section); clock is inactive.
NOTE: VI(3.3V) or VI(5V) must be biased for switches to function.
