PLUS173B/D
DESCRIPTION
The PLUS173 PLDs are high speed,
combinatorial Programmable Logic Arrays.
The Philips Semiconductors state-of-the-art
Oxide Isolated Bipolar fabrication process is
employed to produce propagation delays as
short as 12ns.
The 24-pin PLUS173 devices have a
programmable AND array and a
programmable OR array. Unlike PAL
®
devices, 100% product term sharing is
supported. Any of the 32 logic product terms
can be connected to any or all of the 10
output OR gates. Most PAL ICs are limited to
7 AND terms per OR function; the PLUS173
devices can support up to 32 input wide OR
functions.
The polarity of each output is user-
programmable as either Active-High or
Active-Low, thus allowing AND-OR or
AND-NOR logic implementation. This feature
adds an element of design flexibility,
particularly when implementing complex
decoding functions.
The PLUS173 devices are user-
programmable using one of several
commercially available, industry standard
PLD programmers.

NOTES:
1. For 3-State outputs; output enable times are tested with C
L
= 30pF to the 1.5V level, and S
1
is open for high-impedance to High tests and
closed for high-impedance to Low tests. Output disable times are tested with C
L
= 5pF. High-to-High impedance tests are made to an output
voltage of V
T
= (V
OH
– 0.5V) with S
1
open, and Low-to-High impedance tests are made to the V
T
= (V
OL
+ 0.5V) level with S
1
closed.
2. All propagation delays are measured and specified under worst case conditions.
