Programmable logic array

(22 × 42 × 10)

Product specification

PLUS173–10

DESCRIPTION

The PLUS173–10 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 PLUS173–10 device has 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

PLUS173–10 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 PLUS173–10 device is user-

programmable using one of several

commercially available, industry standard

PLD programmers.
