What are the key features of CD4078BE-NG?
- 8-input single NOR/OR gate provides high fan-in logic compression in a single 14-PDIP package
- Wide 3 V to 15 V supply range with rail-to-rail CMOS output swing for multi-voltage system compatibility
- Ultra-low quiescent current of 1 µA (typ) at 5 V for battery-powered and standby logic circuits
What is CD4078BE-NG used for?
The CD4078BE-NG is used in digital logic systems requiring an 8-input OR or NOR function, such as interrupt combining, bus parity checking, and alarm aggregation circuits. Its wide supply range from 3 V to 15 V makes it compatible with both legacy TTL-level and modern 3.3 V CMOS systems. The through-hole 14-PDIP footprint also makes it a popular choice for educational lab experiments and prototyping breadboards.

Frequently Asked Questions
How many logic inputs does the CD4078BE-NG provide, and what supply voltage range does it support?
The CD4078BE-NG provides 8 logic inputs for a single NOR/OR function and operates from a supply voltage of 3 V to 15 V. This combination allows designers to combine up to 8 independent signal lines into a single high-fan-in gate, covering both 5 V TTL-compatible and 3.3 V CMOS systems without any additional level-shifting components.
For a battery-operated alarm aggregator circuit, how suitable is the CD4078BE-NG in terms of quiescent current draw?
The CD4078BE-NG draws typically just 1 µA quiescent current at 5 V, making it extremely well suited for battery-operated alarm and monitoring circuits that spend most of their time in a standby state. An 8-input OR configuration lets a single IC monitor 8 sensor lines simultaneously, replacing multiple discrete gates and further reducing total system power consumption.
When would a designer choose the CD4078BE-NG over a 2-input or 4-input gate for interrupt logic?
When a microcontroller or FPGA has only one external interrupt pin but must respond to 8 separate peripheral events, the CD4078BE-NG collapses all 8 interrupt lines into a single OR output with no additional glue logic. This saves at least 2 ICs compared to cascading standard 2-input CMOS gates, reduces PCB area by roughly 50%, and keeps propagation delay under 150 ns at 5 V.
