What are the key features of CD74HC4075E?
- Triple 3-input OR gate configuration in a single 14-pin DIP package for compact combinational logic
- Wide supply range of 2 V to 6 V compatible with both 3.3 V and 5 V digital systems
- HC CMOS technology with high noise immunity and low quiescent current for power-sensitive designs
What is CD74HC4075E used for?
CD74HC4075E is used in combinational logic circuits requiring OR functions, such as interrupt aggregation, alarm detection, and event-driven signal merging in embedded systems. Its triple 3-input OR gate topology allows combining up to 3 signals per gate across 3 independent channels from a single IC. The 14-pin DIP package suits through-hole prototyping boards and educational lab designs.

Frequently Asked Questions
How many OR gate channels does CD74HC4075E provide, and how many inputs per gate?
CD74HC4075E provides 3 independent OR gate channels, each with 3 inputs, all in a single 14-pin DIP package. This triple 3-input OR configuration allows combining up to 9 separate logic signals into 3 outputs, saving board space compared to using discrete 2-input OR gates in series.
What supply voltage range does CD74HC4075E support for mixed 3.3 V and 5 V board designs?
CD74HC4075E operates from 2 V to 6 V, covering standard logic supply rails of 3.3 V and 5 V. At 5 V the output drives a 50 pF load with up to 5.2 mA IOL, and CMOS input thresholds at approximately 50% of VCC provide good noise margin across the supply range.
In which applications is CD74HC4075E used for interrupt or alarm signal aggregation?
CD74HC4075E is commonly used to OR together interrupt lines from multiple peripherals before connecting to a single microcontroller IRQ pin, reducing required GPIO count. In alarm systems, 3 sensor outputs can feed one OR gate so that any single sensor triggering asserts the alarm output, simplifying firmware polling logic.
How does CD74HC4075E compare to a CD74HC32 dual 2-input OR gate for the same function?
CD74HC4075E provides 3-input OR in a single gate, whereas CD74HC32 offers only 2-input OR requiring chained gates to achieve 3-input OR, adding propagation delay of approximately 7 ns per stage at 5 V. Using CD74HC4075E saves one IC and reduces total gate delay when OR-ing 3 signals.
