ABT22V10A5, A7

DESCRIPTION

The ABT22V10A is a versatile PAL® device fabricated on Philips

BiCMOS process known as QUBiC.

The QUBiC process produces very high speed, 5 volt devices

(5.0ns) which have excellent noise immunity. The ground bounce of

an output held low while the 9 remaining outputs are switching is

less than 1.0V (typical).

The ABT22V10A outputs are designed to support Live

Insertion/Extraction into powered-up systems. The output is

specially designed so that during VCC ramp, the output remains

3-Stated until VCC ≈ 2.1V. At that time, the outputs become fully

functional, depending upon device inputs. (See DC Electrical

Characteristics, Symbol IPU/PD, Page 4).

The ABT family of devices have virtually no ground bounce— less

than 1.0 volts VOLP, measured on an unswitched output (9 remaining

outputs switching, each with a 50pF load tied to ground).

The ABT family of devices has been designed with high drive

outputs (48mA sink and 16mA source currents), which allow for

direct connection to a backplane bus. This feature eliminates the

need for additional, standalone bus drivers, which are traditionally

required to boost the drive of a standard 16/–4mA PLDs.

Philips has developed a new means of testing the integrity of fuses,

both blown and intact fuses, which insures that all the fuses have

been correctly programmed and that each and every fuse—whether

“blown” or “intact”—is at the appropriate and optimal fuse resistance.

This dual verify scheme represents a significant improvement over

single reference voltage comparison schemes that have been used

for bipolar devices since the late 1980’s.

The ABT22V10A uses the familiar AND/OR logic array structure,

which allows direct implementation of sum-of-products equations.

This device has a programmable AND array, which drives a fixed

OR array. The OR sum-of-products feeds an “Output Macro Cell”

(OMC) that can be individually configured as a dedicated input, a

combinatorial output, or a registered output with internal feedback.
