What are the key features of CD74HC85PWR?
- 4-bit magnitude comparator with cascadable inputs enabling expansion to 8-bit, 12-bit, or wider word comparisons without additional glue logic
- Three comparison outputs (A greater than B, A equal B, A less than B) for direct use in sorting, range-checking, and control logic
- High-speed HC/UH CMOS family with 50 pF load capacitance rating, providing fast propagation in 2 V to 6 V logic systems
What is CD74HC85PWR used for?
The CD74HC85PWR is used in digital control systems requiring real-time magnitude comparison of 4-bit data words, such as address decoding, threshold detection, and priority arbitration circuits. Its cascadable design allows engineers to chain multiple devices for 8-bit or 16-bit comparisons in PLCs, microcontroller peripherals, and embedded digital logic designs.

Frequently Asked Questions
How can multiple CD74HC85PWR devices be cascaded for 8-bit magnitude comparison?
Two CD74HC85PWR devices can be cascaded by connecting the three cascade inputs (A>B, A=B, A<B) of the higher-order stage to the corresponding outputs of the lower-order stage. This expands comparison to 8-bit words using only 2 ICs, each handling 4 bits, with results propagating correctly through the 3-output cascadable interface.
What output sink current does the CD74HC85PWR provide and which loads can it drive directly?
The CD74HC85PWR has a maximum output sink current (I(ol)) of 5.2 mA, which is sufficient to directly drive standard HC-family CMOS logic inputs and small LED indicators in status display circuits. For higher-current loads, a buffer or transistor stage is recommended to avoid exceeding the device's drive capability.
In which industrial monitoring scenario does the CD74HC85PWR provide a cost-effective solution?
In temperature or pressure monitoring systems using 4-bit ADCs, the CD74HC85PWR compares sensor output against a 4-bit threshold value to trigger alarms or control outputs. Its three comparison outputs directly interface with alarm logic, eliminating the need for a microcontroller in simple threshold detection tasks and reducing system cost.
