Overview
The NJU4066BM is a quad bilateral analog switch IC manufactured by Nisshinbo Micro Devices Inc. It features four independent SPST switches controlled by separate logic signals, where the channel conducts when the control input is high and blocks when low. The device utilizes C-MOS technology to support an operating voltage range of 3 V to 18 V. Electrical characteristics include a maximum on-state resistance of 240 Ω at 15 V supply and a quiescent current of up to 5 µA at 18 V. It operates within a temperature range of -40°C to +85°C and is housed in a DMP-14 surface-mount package.
Feature Summary
- Four independent bilateral analog switches with individual control inputs
- Low on-state resistance for superior signal transfer characteristics
- Compatible with standard CMOS logic families for direct interface
Applications
- Analog and digital signal switching circuits
- Chopper-modulator-demodulator systems
- Signal routing in data acquisition systems
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as it varies by production batch and region. Check for Not Recommended for New Designs (NRND) status if considering DIP variants, though the BM variant remains active. Ensure supply chain stability through authorized distributors.
Selection Notes
Select this component for applications requiring multiple isolated signal paths in a compact surface-mount footprint. Compare on-resistance values across different supply voltages to ensure signal integrity meets system requirements. Consider the 18 V maximum rating when designing for higher voltage domains. Verify that the control logic levels align with the specified high-level input voltage thresholds for reliable switching.
Part Context
The NJU4066B series belongs to Nisshinbo's portfolio of C-MOS analog switches. It is functionally and pin-to-pin compatible with legacy parts such as the RCA CD4066B and Motorola MC14066B. This compatibility facilitates drop-in replacements in existing designs while offering modern manufacturing standards and availability in various package options including DMP-14.
Replacement Considerations
Direct functional substitutes include the RCA CD4066B and Motorola MC14066B due to pin-to-pin compatibility. Verify electrical parameters such as on-resistance and leakage current match the original design constraints before substitution.
