Single-supply operation also limits signal levels and
interferes with ground referenced signals. When V- = 0,
AC signals are limited to -0.3V. Voltages below -0.3V
can be clipped by the internal ESD-protection diodes,
and the parts can be damaged if excessive current
flows.
Power Up
During power up, on-chip latches will strobe whatever
addresses are present if EN goes high before LATCH
reaches a logic high. When this condition occurs, one
of the internal dividers connected between the supplies
may immediately turn on, causing higher supply current
(1.4mA) when the enable input is toggled. Avoid this
condition by ensuring that EN stays low until the
remaining logic inputs are valid. To accomplish this,
connect a resistor from EN to ground or apply a low
voltage to EN before the other logic inputs go high.
Power Off
When power to the MAX4578/MAX4579 is off (i.e., V+ =
V- = 0), the Absolute Maximum Ratings still apply. This
means that neither logic-level inputs on NO_ nor sig-
nals on COM_ can exceed ±0.3V. Voltages beyond
±0.3V cause the internal ESD-protection diodes to con-
duct, and the parts can be damaged if excessive cur-
rent flows.
