The circuit diagram of 2-bit magnitude comparator using PTL logic is shown in below Figure 4. We could use a “MSI” medium-scale integration approach here, This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
The devices are expandable without external gating, in both serial and parallel fashion. Design a minimized combinational circuit that will add 9 to a 4-bit number. K-map method can be used to derive the minimized equations to describe the behavior of the.
The package thermal impedance is calculated in accordance with JESD When ordering, use the entire part number. Home Contact Copyright Privacy.
