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.
