Temperature at which devices should be tested ? Room
Ambient and/or Maximum operating Temperature of °C.
Negative
Current Latch-up:
1. Voltage
to which device should be powered V
(Vddq)
2. Please provide a list of input pins with the state
(High or Low) they should be set to
3. Does the device require preconditioning, for
example after power-up?
Yes No If YES, please describe in detail
how the preconditioning should be performed.
4. What value of Icc, the total dc supply current for
the DUT, will be obtained if the device is setup
correctly?mA
(I nom)
5. What
value of Icc will be defined as latch-upmA
(JEDEC 78 recommends I
nom + 10 mA, or 1.4X I nom, whichever is greater.)
6. What value should VddQ be raised to during test?mA
7. The starting trigger current required ismA,
incrementing inmA
steps to a maximum current ofmA.
The trigger voltage should be limited toV.
The duration of the trigger voltage should bems
(JEDEC 78 recommends 10 µs to 5s). The wait time
before Icc will be measured is
(JEDEC 78
recommends 3ms to 5s)
