NE/SA594Vacuum fluorescent display driver
539
August 31, 1994 853-1045 13721
DESCRIPTION
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.
The inputs are designed to be compatible with TTL, DTL, NMOS,
PMOS or CMOS output circuitry.
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.
FEATURES
•Digit and/or segment drivers
•Active output pull–down circuitry
•High output breakdown voltage
•Low supply voltage
•Input compatible with all logic outputs
APPLICATIONS
•Digital clocks
•Dashboard displays
•Panel displays
