Negative-Going VCC Transients
These devices are relatively immune to short-duration,
negative-going VCC transients (glitches).
The Typical Operating Characteristics show the
Maximum Transient Duration vs. Threshold Overdrive
graph, for which output pulses are not generated. The
graph shows the maximum pulse width that a negative-
going VCC transient may typically have before the
devices issue output signals. As the amplitude of the
transient increases, the maximum allowable pulse width
decreases.
UCSP Reliability
The chip-scale package (UCSP) represents a unique
packaging form factor that may not perform equally to a
packaged product through traditional mechanical reliabil-
ity tests. CSP reliability is integrally linked to the user’s
assembly methods, circuit board material, and usage
environment. The user should closely review these areas
when considering use of a CSP package. Performance
through Operating Life Test and Moisture Resistance
remains uncompromised as it is primarily determined by
the wafer-fabrication process.
Mechanical stress performance is a greater considera-
tion for a CSP package. CSPs are attached through
direct solder contact to the user’s PC board, foregoing
the inherent stress relief of a packaged product lead
frame. Solder joint contact integrity must be considered.
Information on Maxim’s qualification plan, test data, and
usage recommendations are detailed in the UCSP appli-
cation note, which can be found on Maxim’s website at
