The FM573 and FM574 are innovative circuits that store inputs like conventional logic families, and then retain the stored state in the absence of power. FM573 and FM574 solve three basic problems in an elegant fashion. First, they provide continuous access to nonvolatile system settings without performing a memory read operation or using dedicated processor I/O pins. Second, they allow the storage of signals or data that may change frequently and possibly without notice. Third, they allow the nonvolatile storage of a few bits of data or system settings without the system overhead and extra pins of a serial memory. The FM573 is a transparent latch. The inputs are passed to the outputs when the clock is high; the state is latched when the clock goes low. The FM574 is a Dtype register. Inputs are stored and passed to the outputs on the rising edge of the clock. The nonvolatile latch is a unique product that serves a variety of applications
