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. 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 PLS153 and PLS153A are
field-programmable, enabling the user to
quickly generate custom patterns using
standard programming equipment.
