This means that the driver can be operated in this
application up to the MAX6920’s +125°C maximum
operating temperature.
The MAX6920 operates with multiple power-supply volt-
ages. Bypass the V
GND with a 0.1µF capacitor close to the device. For
multiplex applications, it may be necessary to add an
additional 1µF bulk electrolytic capacitor, or greater, to
the V
The order of the power-supply sequencing is not impor-
tant. The MAX6920 will not be damaged if either V

is maintained up to its maximum rating. However, as
with any CMOS device, do not drive the MAX6920’s
logic inputs if the logic supply V
because the input protection diodes clamp the signals.
