What are the key features of CD4078BEG4?
- Single 8-input NOR/OR gate enabling zero-detect or any-input-high detection across 8 signal lines in a single IC
- High-voltage CMOS operation from 3 V to 18 V supporting direct interfacing with 12 V and 15 V industrial control systems
- CD4000B-series ultra-low quiescent current below 1 µA making it ideal for battery-operated alarm and supervisory circuits
What is CD4078BEG4 used for?
The CD4078BEG4 is used in digital logic designs where any one of 8 input signals must trigger an output response, such as multi-sensor alarm systems combining up to 8 detection inputs into a single alert output. It is also applied in fault detection circuits where the OR function monitors 8 status lines simultaneously without additional gating logic. The 3 V to 18 V supply range makes it suitable for industrial PLCs, automotive, and battery-powered supervisory systems.

Frequently Asked Questions
How many inputs does the CD4078BEG4 NOR/OR gate have, and what output level does it produce when all inputs are low?
The CD4078BEG4 has 8 inputs on a single gate element. When all 8 inputs are logic low, the NOR output is logic high and the OR output is logic low. Any single high input among the 8 switches the NOR output low, enabling detection of up to 8 independent signal sources with a single IC and no additional components.
What supply voltage range does CD4078BEG4 support, and why is this an advantage over 74HC-series 8-input gates?
The CD4078BEG4 operates from 3 V to 18 V, while 74HC-series equivalents are limited to 2 V to 6 V. This allows CD4078BEG4 to interface directly with 12 V PLC outputs and 15 V analog control signals without level-shifting circuitry, saving 1 to 2 additional components per channel in industrial wiring cabinets.
In a multi-sensor alarm panel, how does CD4078BEG4 reduce wiring complexity compared to software-polled inputs?
A single CD4078BEG4 combines 8 sensor signals at up to 18 V into one hardware OR output, triggering an alarm relay in under 100 ns without CPU intervention. This replaces an 8-channel GPIO polling loop with typical latency of 1 µs to 10 µs, ensuring that no alarm event is missed even if the microcontroller is in a low-power sleep state.
What DIP package does CD4078BEG4 use, and in which application scenarios does through-hole mounting remain preferable to SMT?
The CD4078BEG4 uses a 14-pin DIP package with 2.54 mm pin pitch, suited for through-hole PCB assembly. Through-hole mounting is preferred in high-vibration industrial environments, hobbyist prototyping on breadboards, and repair-friendly field equipment where individual ICs must be socketed and replaced without soldering equipment. The DIP package also simplifies hand-soldering in low-volume production runs.
