What are the key features of CD74HC85PW?
- 4-bit cascadable magnitude comparator with 3 independent outputs (A>B, A=B, A<B) enabling expansion to 8-bit, 16-bit, or wider comparisons by daisy-chaining multiple devices
- High-speed HC CMOS logic family with 50 pF load capacitance rating and 5.2 mA max sink current in a 16-pin R-PDSO-G16 small-outline package
- RoHS-compliant (JESD-609 e4) single-function comparator design optimized for address decoding, sorting networks, and hardware comparison circuits in digital logic systems
What is CD74HC85PW used for?
The CD74HC85PW is used in digital comparison circuits for address decoding, hardware sorting networks, and range checking in programmable logic and FPGA support designs where a dedicated 4-bit comparator reduces combinational logic complexity. Its cascadable inputs allow multiple CD74HC85PW devices to be chained together to compare 8-bit, 12-bit, or larger binary words without additional glue logic. The device also suits industrial PLCs and embedded controllers needing fast hardware-level threshold detection across 4-bit data nibbles.

Frequently Asked Questions
How many bits does the CD74HC85PW compare and can it be expanded for wider word lengths?
The CD74HC85PW compares 4-bit binary values and provides cascadable inputs so multiple devices can be chained to compare 8-bit, 16-bit, or wider words, with each stage adding 4 bits of comparison depth using the A>B, A=B, and A<B cascade inputs and outputs.
What output signals does the CD74HC85PW provide after completing a magnitude comparison?
The CD74HC85PW produces 3 distinct outputs corresponding to the possible comparison results: A greater than B, A equal to B, and A less than B, allowing downstream logic to branch or decode based on which of the 3 conditions is true for the 4-bit input word pair.
What load capacitance does the CD74HC85PW support and what does this mean for signal integrity?
The CD74HC85PW is rated for a 50 pF load capacitance on each output, which sets the maximum capacitive loading for maintaining specified propagation delay and output drive at 5.2 mA sink current; exceeding 50 pF per output will increase delay and degrade signal integrity in high-speed comparison chains.
In which logic family does the CD74HC85PW belong and what supply voltage does the HC family use?
The CD74HC85PW belongs to the HC (high-speed CMOS) logic family, which typically operates from a 2 V to 6 V supply with a nominal 5 V operating point, providing CMOS-compatible input and output levels with lower power consumption than equivalent TTL-series magnitude comparator designs.
