DESCRIPTION
The ABT22V10A is a versatile PAL® device fabricated on Philips Bi CMOS process known as QUBi C.
The QUBi C 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 bee 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 50p F load tied to ground).
The ABT family of devices has been designed with high drive outputs (48m A sink and 16m A 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/- 4m A 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 parison 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 binatorial output, or a registered output with internal feedback.
