| Seeking info about Siemens FZJ logic (1980's) |

| iXod:
Some equipment with a "FZJ101 H4" DIP-16 IC, needs replacement. Best I can determine it's a Siemens dual JK flip-flop. No idea what logic, voltages, etc. it's based on. I'd like to find a datasheet and with the goal of replacing this IC with a modern one and some external circuitry (I think this is a high-voltage type, maybe resistant to noise?). Any help is very much welcome. Thanks. |

So lets try some BASIC info from you, what is the supply voltage, what is the clock frequency ? A picture of the pcb with said part also might be illuminating, sorry ost my crystal ball at the moment! |

IIRC those run off 15VDC, and have quite high noise immunity. Never worked with them, just found some modules in the scrap yard. |
