6118

Consisting of eight npn Darlington output stages and the associatedcommon-emitter input stages, these drivers 6118 are designed tointerface between low-level digital logic and vacuum fluorescentdisplays. Both 6118 are capable of driving the digits and/or segmentsof these displays and are designed to permit all outputs to beactivated simultaneously. Pull-down resistors are incorporated intoeach output and no external components are required for most fluorescent display applications.

With any device, the output load of 6118 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.
