Single-Supply Operation
The MAX4539/MAX4540 operate from a single supply
between +2.7V and +12V when V- is connected to
GND. All of the bipolar precautions must be observed.
However, these parts are optimized for ±5V operation,
and most AC and DC characteristics are degraded sig-
nificantly when departing from ±5V. As the overall sup-
ply voltage (V+ to V-) is lowered, switching speed,
on-resistance, off isolation, and distortion will degrade.
(see the
Typical Operating Characteristics section).
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 inadvertently turn on, causing higher supply current
(~200A supply current) when the enable input is tog-
gled. Avoid this condition by ensuring that EN pin stays
low until the remaining logic inputs are valid. To accom-
plish 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 MAX4539/MAX4540 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.
