What are the key features of CD74HC11EE4?
- Triple 3-input AND gate with three independent logic functions in a 14-pin PDIP package, enabling multi-condition enable gating and combinational logic with high fan-in without cascading
- High-speed CMOS (HC) family operating from 2V to 6V supply combines wide voltage compatibility with fast switching speeds and very low quiescent power consumption
- Industry-standard 74HC11 pinout in a through-hole PDIP package provides breadboard compatibility and direct replacement for legacy CMOS and TTL-equivalent AND gate designs
What is CD74HC11EE4 used for?
The CD74HC11EE4 is used in digital control circuits where multiple conditions must all be true simultaneously before an action is taken, such as multi-input enable logic for bus drivers, chip selects, and interrupt controllers. Its three independent 3-input AND gates allow implementation of complex combinational logic functions in a single compact package. Through-hole PDIP packaging makes it ideal for prototyping, educational use, and maintenance of legacy digital equipment.

Frequently Asked Questions
How many logic functions does the CD74HC11EE4 provide and how are they configured?
The CD74HC11EE4 contains three independent 3-input AND gates. Each gate has three separate inputs and one output, where the output is high only when all three inputs are simultaneously high. This wide fan-in logic function is useful for multi-condition enable circuits and complex combinational logic in a single 14-pin package.
What supply voltage range does the CD74HC11EE4 support?
The CD74HC11EE4 operates from a 2V to 6V supply voltage, making it compatible with both 3.3V and 5V logic systems. This wide operating range allows it to interface directly with modern low-voltage CMOS microcontrollers as well as older 5V TTL-level digital systems without requiring external level translation.
What is the load capacitance specification and what does it mean for circuit design?
The CD74HC11EE4 is characterized at a load capacitance of 50 pF per output. This means the timing specifications such as propagation delay are valid when driving loads up to 50 pF. Higher capacitive loads will increase propagation delays, which designers should account for in timing-critical applications by adding series resistors or buffers.
Is the CD74HC11EE4 compatible with TTL logic levels?
At 5V supply, the CD74HC11EE4 inputs have logic thresholds compatible with 5V TTL output levels (VIH min 3.5V, VIL max 1.0V at VCC=4.5V). However, HC-family devices have slightly different input thresholds than HCT-family devices, which are specifically designed for direct TTL compatibility. For guaranteed TTL-level interfacing, the CD74HCT11 is the recommended alternative.
What are common applications for triple 3-input AND gates like the CD74HC11EE4?
Common applications include multi-input chip select generation for memory and peripheral devices, multi-condition interrupt enable logic, safety interlocking circuits where multiple conditions must be met, and combinational state decoding in finite state machines. The triple gate configuration also allows three independent AND operations sharing a single power supply and PCB footprint.
