4-bit magnitude comparator in a wide-VDD logic family
The CD74HC85E is a 4-bit magnitude comparator from the 74HC family, outputting three active-high signals — A<B, A=B, A>B — so a downstream processor or latch reads the comparison result without decoding a multi-bit bus.
Through-hole integration and timing margin
Housed in a 16-pin PDIP (0.300" body), the CD74HC85E suits prototyping sockets, breadboards, or production boards where wave-solder assembly is preferred over reflow. The 0.100" pin pitch matches standard perfboard and wire-wrapping grids. Quiescent current sits at 8 µA, negligible in a powered system.
No end-of-life notice or successor has been issued — the CD74HC85E remains a standard catalog item for new and existing designs. The part carries full manufacturer traceability and warranty.
