Overview
NTE2028 Integrated Circuit 7–Segment High Voltage Decoder/Driver Description: The NTE2028 is an integrated circuit in a 16–Lead DIP type package custom designed to decode four lines of BCD and drive a gas–filled seven–segment display tube.
Each output constitutes a switchable, adjustable current sink which provides constant current to the tube segment, even with high tube anode supply tolerance or fluctuation.
These current sinks have a voltage compliance from 3V to at least 80V; typically the output current varies 1% for output voltage changes of 3 to 50V.
Each bit line of the decoder switches a current sink on or off as prescribed by the input code.
Each current sink is ratioed to the b–output current as required for even illumination of all segments.
Output currents may be varied over the 0.
2 to 1.
5 mA range for driving various tube types or multiplex operation.
The output current is adjusted by connecting an external program resistor (Rp) from VCC to the Program input in accordance...
