is the “instant on” case temperature.
See the last page of this specification for Group A subgroup testing information.
The CMOS process does not provide a clamp diode. However, the FIFO is insensitive to –3V dc input levels and –5V undershoot pulses of less than 10 ns
(measured at 50% output).
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
Tested initially and after any design or process changes that may affect these parameters.
