ECL programmable array logic
10H20EV8/10020EV8
DESCRIPTION
The 10H20EV8/10020EV8 is an ultra
high-speed universal ECL PAL
廬
device.
Combining versatile output macrocells with a
standard AND/OR single programmable
array, this device is ideal in implementing a
user鈥檚 custom logic. The use of Philips
Semiconductors state-of-the-art bipolar oxide
isolation process enables the
10H20EV8/10020EV8 to achieve optimum
speed in any design. The SNAP design
software package from Philips
Semiconductors simplifies design entry
based upon Boolean or state equations.
The 10H20EV8/10020EV8 is a two-level logic
element comprised of 11 fixed inputs, an
input pin that can either be used as a clock or
12th input, 90 AND gates, and 8 Output Logic
Macrocells. Each Output Macrocell can be
individually configured as a dedicated input,
dedicated output with polarity control, a
bidirectional I/O, or as a registered output
that has both output polarity control and
feedback to the AND array. This gives the
part the capability of having up to 20 inputs
and eight outputs.
The 10H20EV8/10020EV8 has a variable
number of product terms that can be OR鈥檇
per output. Four of the outputs have 12 AND
terms available and the other four have 8
terms per output. This allows the designer the
extra flexibility to implement those functions
that he couldn鈥檛 in a standard PAL device.
Asynchronous Preset and Reset product
terms are also included for system design
ease. Each output has a separate output
enable product term. Another feature added
for the system designer is a power-up Reset
on all registered outputs.
The 10H20EV8/10020EV8 also features the
ability to Preload the registers to any desired
state during testing. The Preload is not
affected by the pattern within the device, so
can be performed at any step in the testing
sequence. This permits full logical verification
even after the device has been patterned.
