6118
A6118SLW
VACUUM FLUORESCENT
DISPLAY DRIVER
Consisting of eight npn Darlington output stages and the associ-
ated common-emitter input stages, these drivers are designed to
interface between low-level digital logic and vacuum fluorescent
displays. Both devices are capable of driving the digits and/or seg-
ments of these displays and are designed to permit all outputs to be
activated simultaneously. Pull-down resistors are incorporated into
each output and no external components are required for most fluores-
cent display applications.
With any device, the output load is activated when the input is
pulled towards the positive supply (active ‘high’). The UDN6118A is
furnished in a standard 18-pin plastic DIP; the A6118SLW is in a 20-
lead wide-body SOIC. Both units operate over the temperature range
of -20°C to +85°C. These devices are also available for operation over
the temperature range of -40°C to +85°C by changing the part number
to UDQ6118A or A6118ELW.

Caution: The high input impedance of these
devices makes them susceptible to static
discharge damage associated with handling and
testing. Techniques similar to those used for
handling MOS devices should be employed.
Always order by complete part number, e.g.,
