The 74HCT85 is a high-speed 4-bit magnitude comparator that is expandable to almost any length. It features serial or parallel expansion without extra gating and has a standard output capability. It ...

Abstract: In this paper an area and power efficient 56T 4-bit comparator design has been presented by using GDI technique. The proposed 4-bit comparator design consist of 28 NMOS and 28 PMOS. A GDI ...

The 74HC/HCT85 are 4-bit magnitude comparators which belong to the high-speed Si-gate CMOS devices. These type of devices can be expanded to any length without extra gating and are pin compatible with ...

This circuit implements a 4-bit magnitude comparator using basic logic gates in Wokwi. Two 4-bit values (A and B) are entered via the DIP switch (sw1). The logic compares whether A > B and outputs the ...

This circuit compares two 4-bit binary inputs, A[3:0] and B[3:0], and checks if they are equal. Working Inputs: Two 4-bit numbers A (A3 A2 A1 A0) and B (B3 B2 B1 B0). The comparator checks each ...
