Vacuum fluorescent display driver |
NE/SA594 |
|
|
|
|
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
