Fluorescent Display Drivers
GENERAL DESCRIPTION
FUNCTIONAL BLOCK DIAGRAM
The XR-6118 and the XR-6128 are high-voltage display
driver arrays which are designed to interface between
low-level digital logic and vacuum fluorescent displays.
Each circuit consists of eight independent signal chan-
nels comprised of Darlington output stages and
common-emitter type inputs. All stages on the chip
share common power supply and ground connections.
Both device types are capable of driving digits and/or
segments of fluorescent displays, and all of the eight
outputs can be activated simultaneously.

SYSTEM DESCRIPTION
The XR-6118 and XR-6128 fluorscent display drivers
can switch up to 85V and 40 mA. Inputs are protected
to 20V. The XR-6118 is compatible with TIL, Schottky
TIL, DTL and 5 Volt CMOS logic families. The XR-6128
is intended for use with PMOS or CMOS logic families
operating with supply voltages of 6V to 15V. The two de-
vice types differ only in their input threshold levels (See
Figure 1). With either device type, the output load is ac-
tivated when the inputs are pulled toward positive sup-
ply. Output pulldown resistors are included on the die.
