Philips Semiconductors Programmable Logic Devices Product specification Programmable logic arrays (18 × 42 × 10) PLS153/A DESCRIPTION The PLS153 and PLS153A are two-level logic elements, 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 8 inputs (I) and 10 bidirectional I/O lines (B). These yield variable I/O gate configurations via 10 direction control gates (D), ranging from 18 inputs to 10 outputs. On-chip T/C buffers couple either True (I, B) or Complement (I, B) input polarities to all AND gates, whose outputs can be optionally linked to all OR gates.
