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.
