Vacuum fluorescent display driver
NE/SA594
DESCRIPTION
PIN CONFIGURATIONS
The NE/SA594 is a display driver interface for vacuum fluorescent
displays. The device is comprised of 8 drivers and a bias network,
and is capable of driving the digits and/or segments of most vacuum
fluorescent displays.

There is an active pull–down circuit on each output so that display
ghosting is minimized and no external components are required for
most fluorescent display applications.
