What are the key features of CD74HC85M96?
- Cascadable 4-bit magnitude comparator with three dedicated outputs (A>B, A=B, A<B) enabling complete magnitude comparison in a single IC
- High-speed HC-family CMOS logic with low propagation delay and 50 pF output load rating for reliable performance in fast digital systems
- 16-pin SOIC surface-mount package allowing compact board layout compared to DIP alternatives, suitable for automated SMT assembly
What is CD74HC85M96 used for?
The CD74HC85M96 is used in embedded controller address decoders, digital sorting networks, and arithmetic logic units where two 4-bit values must be compared rapidly to branch program flow or trigger interrupts. Its cascading inputs allow multiple CD74HC85M96 devices to be chained for 8-bit or 16-bit comparisons in FPGA peripheral circuits, industrial PLC logic expanders, and communication equipment that compares packet sequence numbers or priority fields in real time.

Frequently Asked Questions
How does the CD74HC85M96 differ from the CD4585BE in speed and package, and when should each be chosen?
The CD74HC85M96 belongs to the fast HC CMOS family with propagation delays typically under 15 ns at 5 V, while the CD4585BE is a slower 4000-series device. The CD74HC85M96 also comes in a 16-pin SOIC for SMT assembly, whereas the CD4585BE is offered in a 16-pin DIP for through-hole use, so the HC85M96 suits high-speed SMT designs and the CD4585BE suits prototyping or legacy boards.
What load capacitance can the CD74HC85M96 drive on each output, and what PCB trace length does this support?
Each output of the CD74HC85M96 is rated for 50 pF load capacitance. At 5 V with a typical PCB trace capacitance of 1 pF to 2 pF per centimeter, 50 pF allows trace lengths of roughly 25 cm to 50 cm before additional buffering becomes necessary, covering most intra-board routing without repeaters.
For a 16-bit digital comparator in an FPGA peripheral, how many CD74HC85M96 devices are required and how are they cascaded?
Four CD74HC85M96 devices are needed for a 16-bit comparison, each handling 4 bits. The three outputs (A>B, A=B, A<B) of each lower-significance stage connect to the corresponding cascading inputs of the next higher-significance stage. The final stage's 3 outputs represent the 16-bit comparison result without any additional decode logic.
In a packet-router priority queue sorted by 4-bit priority fields, how does the CD74HC85M96 reduce microcontroller workload?
By offloading the 4-bit comparison to the CD74HC85M96 in hardware, the comparator asserts the A>B, A=B, or A<B output within nanoseconds of valid inputs, whereas a software comparison in a microcontroller requires at least 2 to 4 instruction cycles plus interrupt latency. This hardware acceleration allows the router to sort up to 16 priority levels without consuming any MCU cycles for the comparison step itself.
