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. 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.
