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.
