| INTEGRATED CIRCUITS NE594/SA594 Vacuum fluorescent display driver Product data Supersedes data of 1994 Aug 31 File under Integrated Circuits, IC11 Handbook 2001 Aug 03 Philips Semiconductors Philips Semiconductors Product specification Vacuum fluorescent display driver NE594/SA594 DESCRIPTION The NE594/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.
