It accepts two n-bit binary numbers, say A and B as inputs and produces one of the outputs: Figure a shows the block diagram of n-bit magnitude comparator. Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device.

The circuit diagram of 2-bit magnitude comparator using PTL logic is shown in below Figure 74uct85. The suffixes 96 and. Low Level Input Voltage. Image for Problem Set 2 The devices are expandable without external gating, in both serial and parallel fashion. These devices are sensitive to electrostatic discharge. Design a minimized combinational circuit that will add 9 to a 4-bit number.


Maximum Storage Temperature Range. The inverter at one input of Ex-or make it to act as a Ex-nor which is. Abirami P 1 P, M. Users should follow proper IC Handling Procedures. Understanding decoders and comparators – Electrical Engineering Maximum Lead Temperature Soldering 10s. The upper part of the truth table indicates operation using a single device or devices in a serially.
