Products

UA3533

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.
