Protecting Logic Circuits
For maximum protection of microcomputer equipment, transient suppression must be designed into individual circuit boards. Figure 17.7 illustrates a typical application of on-the-board transient suppression. Multiple voltage-clamping devices are included in a single DIP package, making it possible to
conveniently include protection on individual printed wiring boards. Figure 17.8 shows the application of transient suppressors in a voltage-follower circuit, common in many data-acquisition systems. Note the use of suppression devices at the power-supply pins of the circuits shown in the figures.
