In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, ... got a little confused when converting the circuit to a common anode display. ...

This chip can easily — and cheaply — control eight common cathode seven segment displays. There’s a problem with this plan, though: the LEDs received from eBay are common anode.

The figure shows the circuitry for a two-digit, common-anode display (MAN6710) that can be expanded to any number of digits. Series resistors and the type of latch used limit the segment current.
