Solitron Devices


Solitron Devices, Inc. is an American semiconductor manufacturer.



In 1972, they advertised model UA3533, a single-chip keyboard encoder with 4608 bits of look-up table ROM capacity. The product was advertised as follows:

As a static encoder, this will not be matrix scan. Consequently, this may be a two-of-N encoder, requiring switches with dual isolated outputs. There seems to be no other documented mention of this chip, although it does appear on surplus part sites.


All material was scanned by Bitsavers.
