DESCRIPTION
The PLS159A is a 3-State output, registered
logic element combining AND/OR gate arrays
with clocked J-K flip-flops. These J-K
flip-flops are dynamically convertible to
D-type via a “fold-back” inverting buffer and
control gate F
C
. It features 8 registered I/O
outputs (F) in conjunction with 4 bidirectional
I/O lines (B). These yield variable I/O gate
and register configurations via control gates
(D, L) ranging from 16 inputs to 12 outputs.
The AND/OR arrays consist of 32 logic AND
gates, 13 control AND gates, and 21 OR
gates with fusible link connections for
programming I/O polarity and direction. All
AND gates are linked to 4 inputs (I),
bidirectional I/O lines (B), internal flip-flop
outputs (Q), and Complement Array output
(C). The Complement Array consists of a
NOR gate optionally linked to all AND gates
for generating and propagating
complementary AND terms.
On-chip T/C buffers couple either True (I, B,
Q) or Complement (I, B, Q, C) input polarities
to all AND gates, whose outputs can be
optionally linked to all OR gates. Any of the
32 AND gates can drive bidirectional I/O lines
(B), whose output polarity is individually
programmable through a set of Ex-OR gates
for implementing AND-OR or AND-NOR logic
functions. Similarly, any of the 32 AND gates
can drive the J-K inputs of all flip-flops. There
are 4 AND gates for the Asynchronous
Preset/Reset functions.
All flip-flops are positive edge-triggered and
can be used as input, output or I/O (for
interfacing with a bidirectional data bus) in
conjunction with load control gates (L),
steering inputs (I), (B), (Q) and
programmable output select lines (E).
The PLS159A is field-programmable,
enabling the user to quickly generate custom
patterns using standard programming
equipment.
