Features, Applications

The DS8884A is designed to decode four lines of BCD input and drive seven-segment digits of gas-filled readout displays All outputs consist of switchable and programmable current sinks which provide constant current to the tube cathodes even with high tube anode supply tolerance Output currents may be varied over the 2 mA range for multiplex operation The output current is adjusted by connecting an external program resistor (RP) from VCC to the program input in accordance with the programming curve Unused outputs must be tied to VCC


Usable with or DC input coupling Current sink outputs High output breakdown voltage Low input load current Intended for multiplex operation Input pullups increase noise immunity Comma d pt drive

Note 1 ``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed They are not meant to imply that the devices should be operated at these limits The table of ``Electrical Characteristics'' provides conditions for actual device operation Note 2 Unless otherwise specified min max limits apply across the 70 C temperature range for the DS8884A All typical values are for 25 C and VCC e 5V Note 3 All currents into device pins shown as positive out of device pins as negative all voltages referenced to ground unless otherwise noted All values shown as max or min on absolute value basis Note 4 This limit can be higher for a current limiting voltage source Note 5 In all applications transient segment output current must be limited 50 mA This may be accomplished in DC applications by connecting 2 2k resistor from the anode-supply filter capacitor to the display anode or by current limiting the anode driver in multiplex applications
