PLS173

Programmable logic array

(22

× 42 × 10)

853–0324 11164

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.
