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 ...

In VLSI applications, area, delay and power are the important factors which must be taken into account in the design of a fast adder. The paper attempts to examine the features of certain adder ...

Low power 8 bit GDI magnitude comparator is proposed in this paper which has an advantage of minimum power dissipation, reduced propagation delay and less number of transistors required as compare to ...

The 74HC/HCT688 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT688 are 8-bit ...

Digital comparison is considered an important method used in digital systems while executing arithmetic or logical operations. It’s designed to compare the relative magnitudes of binary numbers. This ...
