描述 Description

DESCRIPTION
The PLS173 is a two-level logic element consisting of 42 AND gates and 10 OR gates with fusible link connections for programming I/O polarity and direction. All AND gates are linked to 12 inputs (I) and
10 bidirectional I/O lines (B). These yield variable I/O gate configurations via 10 direction control gates (D), ranging from 22 inputs to 10 outputs.FEATURES
