Abstract
A CPLD employs a low-voltage, non-degenerative transmitter circuit to eliminate the need for a dedicated control pin to provide the relatively high voltage levels required to verify the program states of programmable memory cells. Eliminating the need for a dedicated control pin frees up valuable chip real estate for the inclusion of an additional general-purpose input/output pin.
