Product specification
Programmable logic array (22 x 42 x 10)
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(R) 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 complex decoding functions. The PLUS173-10 device is userprogrammable using one of several commercially available, industry standard PLD programmers.

NOTES: 1. For 3-State outputs; output enable times are tested with CL = 30pF to the 1.5V level, and S1 is open for high-impedance to High tests and closed for high-impedance to Low tests. Output disable times are tested with CL = 5pF. High-to-High impedance tests are made to an output voltage of VT = (VOH - 0.5V) with S1 open, and Low-to-High impedance tests are made to the VT = (VOL + 0.5V) level with S1 closed. 2. All propagation delays are measured and specified under worst case conditions.

LOGIC PROGRAMMING
The PLUS173-10 is fully supported by industry standard (JEDEC compatible) PLD CAD tools, including Philips Semiconductors SNAP design software package. ABELTM and CUPLTM design software packages also support the PLUS173-10 architecture. All packages allow Boolean and state equation entry formats. SNAP, ABEL and CUPL also accept, as input, schematic capture format. PLUS173-10 logic designs can also be generated using the program table entry format, which is detailed on the following page. This program table entry format is supported by SNAP only. To implement the desired logic functions, the state of each logic variable from logic equations (I, B, O, P, etc.) is assigned a symbol. The symbols for TRUE, COMPLEMENT, INACTIVE, PRESET, etc., are defined below.

NOTES: 1. This is the initial unprogrammed state of all link pairs. It is normally associated with all unused (inactive) AND gates Pn, Dn. 2. Any gate Pn, Dn will be unconditionally inhibited if both the true and complement of any input (I, B) are left intact.
