MM5823 replacement 6-stage frequency divider SP5823
The SP5823 is a drop-in replacement for the obsolete MM5823N Divider IC used in many Moogs and other vintage synthesizers & organs. If multiple keys of the same note are dead it’s likely due to a defect divider IC chip. This is a drop in replacement.
MM5823 is used in these synthesizer and much more instruments:
- Moog Liberation
- Moog MG-1
- Moog Polymoog
- Lowrey C500 Celebration
- Lowrey TGS Symphonic Holiday
These frequency dividers provide six stages of binary division to produce six octave-related outputs of an electronic musical instrument tone generator. Each divider stage consists of an asynchronous, dc-coupled flip-flop .
The IC is housed in a DIP 14 package and is designed for trughhole mounting on a circuit board.
The IC is permanently soldered onto a circuit board. Replacement requires manual dexterity and soldering experience.
ICs are sensitive to static charge!
