Philips Semiconductors Programmable Logic Devices
Product specification
Programmable logic arrays (22 × 42 × 10)
PLUS173B/D
DESCRIPTION
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. The 24-pin PLUS173 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 PLUS173 devices can support up to 32 input wide OR functions. The polarity of each output is userprogrammable 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 devices are userprogrammable using one of several commercially available, industry standard PLD programmers.
