Alternative Part Number

  • UPD71055C --: Pin-compatible parallel peripheral interface (PPI) device in the same class as the MB40978, widely available and functionally equivalent for most I/O expansion applications.
  • 82C55A --: Industry-standard programmable peripheral interface with equivalent 24-line I/O functionality; a well-documented replacement when timing and package constraints allow.
  • W82C55A --: CMOS clone of the 8255A PPI offering comparable I/O capability and lower power, suitable as a functional substitute for the MB40978.
  • TDA2822M --: Widely available dual low-voltage audio power amplifier in DIP-8, commonly used as a substitute for small Fuji audio amplifier ICs like the MB40978.
  • LM386N-1 --: Popular low-voltage audio power amplifier in DIP-8 with similar supply range and output capability, easy to source and well documented.
  • NJM2073D --: Dual audio power amplifier in DIP-8 with comparable supply voltage and output power, a common Japanese-market alternative to Fuji audio ICs.
  • TDA2003 --: Class AB audio power amplifier in the same low-power audio IC class, widely available and commonly used as a substitute in similar audio output stages.
  • LM386 --: Popular low-voltage audio power amplifier IC with similar small-signal audio amplification role, easy to source and well documented.
  • TDA2030A --: Audio power amplifier IC with comparable output capability, often used as a replacement in audio amplifier circuits when the original is unavailable.
