DESCRIPTION
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.
