What are the key features of CD74HC85MTE4?
- 4-bit magnitude comparator with three outputs (A>B, A=B, A<B) enabling direct greater-than, equal, and less-than decisions in a single 16-pin package
- Cascadable design allows expansion to 8-bit, 12-bit, or 16-bit word comparisons by chaining multiple devices without external glue logic
- HC CMOS family with 50 pF load capacitance delivers high-speed comparison for address decoding and arithmetic logic unit (ALU) applications
What is CD74HC85MTE4 used for?
The CD74HC85MTE4 is used in ALU and address-decoding circuits where a 4-bit word must be compared against a reference value to generate greater-than, equal, or less-than status flags for conditional branching logic. Its cascadable inputs allow designers to build 8-bit or 16-bit comparators by chaining two or four devices, making it suitable for range detection in industrial sensor controllers and programmable threshold alarms. It also appears in sorting networks and priority encoders in digital signal-processing hardware where fast 50 pF-rated magnitude comparison is required.

Frequently Asked Questions
How can multiple CD74HC85MTE4 devices be cascaded to compare 8-bit or 16-bit words?
The CD74HC85MTE4 provides dedicated cascade input pins (IA>B, IA=B, IA<B) that accept the comparison outputs of a less-significant stage, allowing two devices to compare 8-bit words and four devices to compare 16-bit words without additional glue logic. The least-significant stage is initialized with IA=B high and IA>B, IA<B low, and each subsequent stage propagates the result upward. The 50 pF load-rated outputs can drive the cascade inputs of the next stage directly within HC-family timing budgets.
In an industrial threshold-alarm controller, how does the CD74HC85MTE4 detect when a 4-bit sensor code exceeds a set-point?
The sensor's 4-bit ADC output is connected to the A inputs of the CD74HC85MTE4, and the set-point value is hard-wired or latched onto the B inputs. When the sensor reading exceeds the set-point, the A>B output goes high, directly triggering an alarm relay or interrupt line without any software intervention. The 5.2 mA sink current at the A>B output is sufficient to drive an optocoupler LED or a logic-level MOSFET gate in typical alarm circuits.
What SOIC package characteristics make the CD74HC85MTE4 suitable for automated production assembly in control boards?
The 16-pin SOIC package of the CD74HC85MTE4 has a standard 1.27 mm pin pitch that is compatible with all common SMT reflow profiles and automated pick-and-place machines, ensuring high-yield assembly at production volumes. The package footprint is approximately 100 mm², providing enough pad clearance for reliable solder joints even on boards with 50 pF bus capacitance, and the SOIC outline is supported by every major PCB CAD library, reducing design time for new control board layouts.
