PLUS173-10 Datasheet | NXP Semiconductors

DESCRIPTION The PLUS173- 10 PLD is a high speed, binatorial 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 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 plex decoding functions. The PLUS173- 10 device is userprogrammable using one of several mercially available, industry standard PLD programmers.
