Philips Semiconductors Programmable Logic Devices

Product specification

Programmable logic arrays

(22 × 42 × 10)

PLUS173B/D

DESCRIPTION

FEATURES

PIN CONFIGURATIONS

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.

• I/O propagation delays (worst case)

– PLUS173B – 15ns max.

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.

• Programmable output polarity

– Active-High or Active-Low

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.
