PLUS173鈥?0
DESCRIPTION
The PLUS173鈥?0 PLD is a high speed,
combinatorial Programmable Logic Array.
The Philips Semiconductors state-of-the-art
Oxide Isolated Bipolar fabrication process is
employed to produce maximum propagation
delays of 10ns or less.
The 24-pin PLUS173鈥?0 device has a
programmable AND array and a
programmable OR array. Unlike PAL
廬
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鈥?0 device 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鈥?0 device is user-
programmable using one of several
commercially available, industry standard
PLD programmers.
