National Semiconductor - MM5740AAD/N - IC. Keyboard Encoder circuit. DIP40
National Semiconductor - MM5740AAD/N IC.
Got a dead keyboard? It’s likely you need to replace the encoder chip. This is the MM5740AAD/N 40-pin chip. Make sure this is the chip you need. The MM5740AAD/N should be used to replace encoder chips of the identical P/N. Please be aware that MM5740AAD/N is not interchangeable with the MM5740AAE/N encoder.
Status: Discontinued
Capable of encoding 90 SPST switch closures into a useable 9-bit code.
Package: 40 DIP.
Note: Clean Socket Pulls.
Used/Removed from equipment. Very nice with clean shiny leads.
