Data Sheet 29313D* 6118 VACUUM FLUORESCENT DISPLAY DRIVER A6118SLW 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 V BB 12 10 NC NC 11 Consisting of eight npn Darlington output stages and the associated 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 segments 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 fluorescent display applications. T C U D O R . y P nl 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 20lead 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.
