Product specification
PLUS153B/D
DESCRIPTION
The PLUS153 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 20-pin PLUS153 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 PLUS153
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 PLUS153 devices are
user-programmable using one of several
commercially available, industry standard
PLD programmers.
