PLS173

Programmable logic array
(22 × 42 × 10)

October 22, 1993 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.

TYPICAL PRODUCT TERM:

Pn = A ⋅ B

TYPICAL LOGIC FUNCTION:

AT OUTPUT POLARITY = H

Z = P0 + P1 + P2 . . .

AT OUTPUT POLARITY + L

Z = P0 + P1 + P2 +

. . .

Z = P0

⋅ P1 ⋅ P2 ⋅ . . .

NOTES:

1. For each of the 10 outputs, either function Z
(Active-High) or Z

(Active-Low) is available, but not
both. The desired output polarity is programmed
via the EX-OR gates.

2. ZX, A, B, C, etc. are user defined connections to
fixed inputs (I), and bidirectional pins (B).

The PLS173 is also processed to military
requirements for operation over the military
temperature range. For specifications and
