Datasheet

The XL2800 is a 1-to-1 replacement for the popular, but obsolete driver IC FP2800A. It's identical in pin assignment, form factor and even slightly better in functionality. If you have a defective flipdot or electromechanical 7-segment display, it might be due to a broken FP2800A. In this case, you can just replace it with an XL2800!
It is a 5:28 multiplexer with open-drain outputs in half-bridge configuration. At any time, one of 28 outputs can be pulled either to ground or to the positive power supply voltage (up to 50 V at 500 mA max.). The integrated clamping diodes protect the XL2800 from voltage spikes which occur when switching inductive loads.

IMPORTANT: In case you're using the XL2800 in a custom circuit, make sure to leave none of the inputs unconnected. There has to be a defined potential of either GND or VCC at any time!
