discontinued product for reference only . 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 ?igh?. 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 ud q6118a or a6118 elw. features digit or segment drivers low input current integral output pull-down resistors high output breakdown voltage single or split supply operation automotive capable always order by complete part number, e.g., udn6118a . absolute maximum ratings at t a = +25 c supply voltage, v bb . . . . . . . . . . . . . . . 85 v input voltage, v in . . . . . . . . . . . . . . . . . 20 v output current, i out . . . . . . . . . . . . -40 ma allowable package power dissipation, p d . . . . . . . . . . . . . . . . . . . . see graph operating temperature range, t a . . . . . . . . . . . . . . . . . -20 c to +85 c storage temperature range, t s . . . . . . . . . . . . . . . -55 c to +150 c 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. data sheet 29313d* a6118slw 13 14 15 16 17 19 12 18 20 11 1 2 3 8 9 4 5 6 7 10 nc nc dwg. pp-064-3 v bb vacuum fluorescent display driver 6118
