Three fully-decoded deci-sions about two, 4-bit words (A, B) are made and are exter-nally available at three outputs. 74LS85 Pin Configuration . 5: Prototype of SN7485 IC based 4-Bit Magnitude Comparator. For more bit comparison, more than one such ICs can be cascaded. straight binary or BCD codes Three fully-decoded decisions. 4-Bit Magnitude Comparators. Circuit Description. The LEDs are connected at the output pins of the IC such that on HIGH output they start glowing. In a previous tutorial – Arithmetic Circuits, digital circuits for performing arithmetic operations were designed. are compared with a reference value. of electronic components including IC's, transistors, diodes, LED's, They are also used in control applications in which the binary numbers representing physical variables such as temperature, position, etc. This circuit demonstrates how to interconnect multiple 7485 chips to build an n-bit comparator.In the example, six chips are uses to create a 24-bit magnitude comparators for positive binary numbers (note that the comparison also works for binary-coded decimal numbers). The circuit is based on the working of the SN7485 IC. The 16-pin IC has the following pin configuration – Fig. In the first level of logic, using the NAND and AND-OR-INVERT gates, the corresponding bits of the A and B inputs are compared. manufacturers, universities and hobbyists. ... To compare more than 4 bits, connect the outputs to … A digital comparator is widely used in combinational systems and is specially designed to compare the relative magnitudes of binary numbers. 4 BIT COMPARATOR (IC 7485) ABSTRACT: To study and simulate design of 4bit comparator IC 7485 using VHDL. The four bit inputs are weighted (A0-A3) and (B0-B3), where A3&B3 are the most significant bits. Integrated Circuits > Like two 4-bit comparators can be cascaded for comparison of 8-bit numbers. 74 Series, Compares 4-bit Binary or BCD Codes and Outputs Greater, Less Than or Equal, Outputs Directly Interface to CMOS, NMOS and TTL, Not Recommended for New Designs Use 74LS85, Switching Characteristics at Vcc=5V,Ta=25°C, Futurlec is a worldwide supplier of quality electronic components to Be the first to review “8 bit Comparator with two 4 bit Comparator in cascade” Cancel reply. IC 74LS85 receives 8 parallel inputs for two 4-bit binary data and gives the output in 3-bit in parallel form. The Integrated Circuit (IC) available for 4 bit digital comparator is IC 7485.
