What are the key features of CD74HC85M?
- Cascadable architecture allows multiple CD74HC85M devices to be chained for comparing words wider than 4 bits without external logic
- Three comparison outputs (A>B, A<B, A=B) provide direct magnitude comparison results for sorting and threshold detection circuits
- Wide 2V to 6V supply range gives flexibility across 3.3V and 5V CMOS logic systems
- HC CMOS family delivers low quiescent current and high noise immunity for reliable operation in industrial and consumer electronics
What is CD74HC85M used for?
The CD74HC85M is used in digital sorting networks, address decoding, data validation circuits, and control systems where two 4-bit binary values must be compared in real time to determine their relative magnitude. By cascading multiple devices, designers can extend comparisons to 8-bit, 16-bit, or wider words, making it a versatile building block in arithmetic logic units, priority encoders, and range-detection circuits.

Frequently Asked Questions
What does the CD74HC85M compare and what outputs does it provide?
The CD74HC85M compares two 4-bit binary numbers (A and B) and produces three non-inverting outputs indicating whether A is greater than B, A is less than B, or A equals B. These simultaneous outputs allow downstream logic to immediately branch on any of the three possible comparison results without additional gate logic.
How can the CD74HC85M be cascaded for wider comparisons?
The device includes dedicated cascading inputs (I(A>B), I(A<B), I(A=B)) that accept the comparison outputs from a less-significant stage. By connecting the outputs of one CD74HC85M to the cascade inputs of the next, designers can compare 8-bit, 12-bit, 16-bit, or wider words using multiple cascaded devices without any additional combinational logic.
What supply voltage range does the CD74HC85M support?
The CD74HC85M operates from a supply voltage of 2V to 6V, covering both 3.3V and 5V CMOS logic systems. This wide range makes it compatible with modern microcontroller I/O lines at 3.3V as well as legacy 5V TTL-compatible designs, providing flexibility in mixed-voltage or multi-generation system boards.
What package does the CD74HC85M come in?
It is housed in a 16-pin SOIC (Small Outline Integrated Circuit) surface-mount package, JESD-30 code R-PDSO-G16. The SOIC footprint is one of the most common SMT package styles, widely compatible with automated PCB assembly equipment, and the 16-pin count comfortably accommodates the device's four data inputs per word plus cascade and output pins.
What is the load capacitance rating for the CD74HC85M outputs?
The CD74HC85M outputs are rated for a load capacitance of 50pF. This specification reflects the maximum capacitive load the device can drive while maintaining its rated propagation delay performance. For applications with heavier capacitive loads such as long PCB traces or bus connections, a buffer stage should be added to prevent signal integrity degradation.
