Overview

Philips Semiconductors Programmable Logic Devices Product specification Programmable logic array (22 × 42 × 10) PLS173 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.
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.
Their output polarity, in turn, is individually programmable through a set of EX-OR gates for implementing AND/OR or AND/NOR logic functions.
The PLS173 is field programmable, enabling the user to quickly generate custom patterns using standard programming equipment.
Order codes for this device are listed below.
