What are the key features of CD74HC7266M96?
- Quad 2-input XNOR gates with 4 independent functions in a compact 14-pin SOIC for logic equivalence detection
- Wide 2 V to 6 V supply range compatible with 3.3 V and 5 V CMOS logic families without level translation
- HC CMOS technology delivering low quiescent current under 80 µA for power-sensitive battery-operated applications
What is CD74HC7266M96 used for?
The CD74HC7266M96 is used in digital comparator circuits, parity bit generators, and error detection logic where bit-by-bit equality checking between two data words is required. Four XNOR gates allow simultaneous comparison of 4 bit-pairs, producing a logic-high output for each matched pair to drive downstream AND gates for full-byte equality detection. Its SOIC-14 package is well suited for compact PCB layouts in industrial data acquisition and communication interface circuits.

Frequently Asked Questions
How can the 4 XNOR gates in CD74HC7266M96 be combined to build a 4-bit digital comparator?
Each of the 4 XNOR gates in CD74HC7266M96 compares one pair of input bits, outputting logic high when both inputs are equal. Connecting all 4 XNOR outputs to a 4-input AND gate creates a full 4-bit equality detector that asserts high only when all 4 bit-pairs match. This configuration compares two 4-bit words in a single propagation delay of approximately 15 ns at 5 V, using just 2 ICs.
What is the maximum output sink current of CD74HC7266M96 and which logic levels can it reliably drive?
The CD74HC7266M96 sinks up to 5.2 mA per output. At 5 V supply this keeps VOL below 0.33 V when sinking full rated current, meeting TTL VIL = 0.8 V input requirements with over 450 mV noise margin. This current capability allows direct interfacing to standard HC and LS-TTL gate inputs without bus buffers for fan-out counts up to 10 standard HC loads.
In a battery-powered embedded system, how does CD74HC7266M96 compare to CMOS unbuffered XNOR solutions for quiescent power?
The CD74HC7266M96 in HC CMOS technology draws typically under 80 µA quiescent supply current at 5 V with inputs static. Compared to NMOS or bipolar XNOR implementations that draw milliamps, this sub-100 µA standby current extends battery life significantly in low-duty-cycle circuits. For a coin-cell powered parity checker active only 1% of the time, average current drops below 1 µA, enabling years of battery operation from a CR2032.
Why might a designer select CD74HC7266M96 over CD74HC86 XOR gates when implementing equivalence logic?
CD74HC7266M96 provides XNOR (equivalence) outputs directly, outputting logic 1 when inputs are equal without requiring an inverter after each XOR gate. Using XOR gates from CD74HC86 instead would require 4 additional inverters to produce equivalence signals, adding an extra propagation delay of approximately 10 ns at 5 V and doubling the IC count. CD74HC7266M96 reduces the solution to a single 14-pin SOIC, saving PCB area and approximately 1 mW of dynamic power.
