The CD74HCT85E is a digital magnitude comparator manufactured by Texas Instruments. It provides the capability to compare two 4-bit binary numbers, offering three outputs that indicate whether one number is less than, equal to, or greater than the other (A<B, A=B, A>B). It operates with a voltage range of 4.5V to 5.5V and features active-high outputs. The device can drive a standard output current of up to 4mA, and it has a propagation delay time of approximately 40 nanoseconds at 4.5V with a capacitive load of 50pF. The package type is a 16-pin Dual In-line Package (PDIP), which facilitates integration into various electronic circuits.
