● 8-pin “Green”/RoHS SOT-23 Package Overview First, it provides continuous access to nonvolatile system settings without performing a memory read operation or using dedicated processor I/O pins. Second, it allows the storage of signals that may change frequently and possibly without notice. Third, it allows the nonvolatile storage of a system setting without the system overhead and extra pins of a serial memory. Functionally, the inputs are stored and passed to the output on the rising edge of the clock CLK. This unique product serves a variety of applications. Here are a few applications: ! ! ! ! ! Control relays or valves with automatic setting on power-up without processor intervention Interface to soft/momentary front-panel switch and indicator lamp.
