Overview
The NJU4066BD is a quad bilateral analog switch manufactured by Nisshinbo Micro Devices Inc. utilizing C-MOS technology. It features four independent switches controlled by separate signals, turning ON at logic HIGH and OFF at logic LOW. The device supports an operating voltage range of 3V to 18V. At 5V supply, the on-state resistance maximum is 850Ω; at 10V, it is 400Ω; and at 15V, it is 300Ω. Quiescent current reaches 150µA maximum at 20V. The component is housed in a DIP-14 package.
Feature Summary
- Four independent bilateral analog switches with individual control inputs
- Low on-state resistance enabling wide input voltage range transfer
- Functionally and pin-to-pin compatible with RCA CD4066B and Motorola MC14066B
Applications
- Analog and digital signal switching
- Chopper-modulator-demodulator circuits
- Signal routing in instrumentation systems
Procurement Notes
Verify the specific ordering suffix for the required package type. The BD suffix indicates a DIP-14 package. Note that the DIP-14 configuration is designated as Not Recommended for New Design (NRND) as of February 2023. Confirm availability and lead times directly with the manufacturer or authorized distributors before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring multiple isolated analog signal paths controlled by digital logic levels. Ensure the supply voltage remains within the 3V to 18V range. Consider the on-state resistance variation across different supply voltages and temperature ranges (-40°C to +85°C). Evaluate alternative packages like DMP-14 or SSOP-14 if surface-mount solutions are preferred due to the NRND status of the DIP package.
Part Context
The NJU4066B series belongs to Nisshinbo Micro Devices' lineup of C-MOS analog switches. This family provides general-purpose signal switching capabilities suitable for various industrial and consumer applications. The device serves as a direct replacement for legacy CMOS analog switches from other manufacturers, facilitating design continuity in existing systems.
Replacement Considerations
The NJU4066BD is functionally equivalent to the RCA CD4066B and Motorola MC14066B. These parts can be used as direct substitutes in designs where pin compatibility and electrical characteristics align with the system requirements.
