DI-8884A High Voltage Cathode Decoder/Driver

Direct Replacement for National DM-8884A

General Description:

Features:

The DI-8884A is designed to decode four

lines of BCD input and drive seven segment

digits of gas-filled readout displays. Two

separate inputs are provided for driving the

decimal point and comma cathodes.

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 0.2

to 1.2 mA range for multiplex operation.

The output current is adjusted by connecting

an external program resistor (Rp) from Vcc to

the program input.
