Philips Semiconductors Programmable Logic Devices Product specification PLUS173–10 Programmable logic array (22 × 42 × 10) 41 October 22, 1993 853–1422 11164 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. FEATURES • I/O propagation delays – 10ns (worst case) • Functional superset of 20L10 and most other 24-pin combinatorial PAL devices • Two programmable arrays – Supports 32 input wide OR functions • 12 inputs • 10 bi-directional I/O • 42 AND gates – 32 logic product terms – 10 direction control terms • Programmable output polarity – Active-High or Active-Low • Security fuse • 3-State outputs • Power dissipation: 850mW (typ.) • TTL Compatible APPLICATIONS • Random logic • Code converters • Fault detectors • Function generators • Address mapping • Multiplexing PIN CONFIGURATIONS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 N Package I0 I1 I2 I3 I4 I5 I6 I7 I8 I9 I10 VCC B9 B8 B7 B6 B5 B4 B3 B2 B1 B0 I11 GND A Package N = Plastic Dual In-Line (300mil-wide) I0 I1 I2 I3 VCC B9 B8 NC I4 I5 I6 I7 I8 NC I9 I10 GND I11 B0 B1 B2 NC B3 B7 B6 B5 B4 NC A = Plastic Leaded Chip Carrier ORDERING INFORMATION DESCRIPTION tPD (MAX) ORDER CODE DRAWING NUMBER 24-Pin Plastic Dual In-Line 300mil-wide 10ns PLUS173–10N 0410D 28-Pin Plastic Leaded Chip Carrier 10ns PLUS173–10A 0401F ®PAL is a registered trademark of Advanced Micro Devices Corporation. |
