... GAL26CV12 eliminates the learning curve typically associated with using a new device architecture. The generic architecture provides maximum design flexibility by allowing the Output Logic Macrocell (OLMC configured by the user. The GAL26CV12 OLMC is fully compatible with the OLMC in standard bipolar and CMOS 22V10 devices. ...

... AND array, with both the true and complement of the feedback available as inputs to the AND array. Specifications GAL26CV12 The GAL26CV12 has a product term for Asynchronous Reset (AR) and a product term for Synchronous Preset (SP). These two prod- uct terms are common to all registered OLMCs. The Asynchronous Reset sets all registered outputs to zero any time this dedicated product term is asserted ...

... OUTPUT REGISTER ACTIVE HIGH OUTPUT REGISTER Circuitry within the GAL26CV12 provides a reset signal to all reg- isters during power-up. All internal registers will have their Q outputs set low after a specified time (tpr MAX result, the state on the registered output pins (if they are enabled) will be either high or low on power-up, depending on the programmed polarity of the output pins ...
