    I have constructed the attached circuit on a breadboard and it works. The clock pulse to the 4022 is a + 15 VDC signal, and the outputs from the 4022 are also + 15V. The outputs from the 2981A are + 15V too, but I need to convert them to + 24V for the CNC control board inputs.

    Any ideas would be greatly appreciated.

    Use the UDN2981A Driver with 24 operating volatge instead of the 15 V currently used.
