DESCRIPTION
The Philips Semiconductors PLUS16XX
family consists of ultra high-speed 7.5ns and
10ns versions of Series 20 PAL devices.
The PLUS16XX family is 100% functional
and pin-compatible with the 16L8, 16R8,
16R6, and 16R4 Series devices.
The sum of products (AND-OR) architecture
is comprised of 64 programmable AND gates
and 8 fixed OR gates. Multiple bidirectional
pins provide variable input/output pin ratios.
Individual 3-State control of all outputs and
registers with feedback (R8, R6, R4) is also
provided. Proprietary designs can be
protected by programming the security fuse.
The PLUS16R8, R6, and R4 have D-type
flip-flops which are loaded on the
Low-to-High transition of the clock input.
In order to facilitate state machine design and
testing, a power-up reset function has been
incorporated into these devices to reset all
internal registers to Active-Low after a
specific period of time.
The Philips Semiconductors State-of-the-Art
oxide isolation Bipolar fabrication process is
employed to achieve high-performance
operation.
The PLUS16XX family of devices are field
programmable, enabling the user to quickly
generate custom patterns using standard
programming equipment. See the
programmer chart for qualified programmers.
The SNAP software package from Philips
Semiconductors supports easy design entry
for the PLUS16XX series as well as other
PLD devices from Philips Semiconductors.
The PLUS16XX series are also supported by
other standard CAD tools for PAL-type
devices.
Order codes are listed in the Ordering
Information table.
