Scheme implements multiple output ports - 02/16/98 EDN-Design Ideas....In
µP/µC systems, you sometimes need to use many output ports and update all the ports
simultaneously. For instance, in systems that use multiplexing techniques, the output
ports require refreshing for every scanning period. One example is a system of
multiple dot-matrix LEDs....File has many circuits, scroll to find this one....[Design

Scheme Speeds Access to µP's Real Time Clock - 06/04/98 EDN-Design
Ideas.... Amplitude limiters are necessary in many systems, such as radar and FM
receivers, for which the system cannot allow the amplitude of the signal to exceed the
given positive, negative, or both limits. In the circuit in Figure 1, amplifier IC4B's
