MC14066BDR2

Overview

The MC14066BDR2G is a quad analog switch manufactured by onsemi, housed in a 14-pin SOIC package. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55°C to +125°C. The device features four independent bilateral switches with a maximum on-resistance of 280 Ohms at 15 V supply. Key electrical parameters include a propagation delay of up to 40 ns, turn-on time of 120 ns, and turn-off time of 80 ns. It offers a bandwidth of 65 MHz and feedthrough attenuation of 50 dB.

Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards and lead-free requirements as specified in the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a low-cost, pin-compatible replacement for legacy CD4016 designs is needed. Consider the HC4066 if lower on-resistance and higher speed are critical requirements. Ensure the application voltage does not exceed the recommended maximum difference between VDD and VSS to maintain optimal parameter performance.

Part Context

This part belongs to the MC14066B series of quad analog switches produced by onsemi. It is designed as a direct drop-in replacement for older CMOS analog switch technologies, offering improved on-resistance characteristics while maintaining standard pin assignments for easy integration into existing circuit layouts.

Replacement Considerations

The MC14066BDR2G serves as a pin-for-pin replacement for the CD4016 and MC14016B. For applications requiring lower on-resistance, the HC4066 high-speed CMOS device is the designated alternative.

FAQ

What is the maximum recommended voltage difference between VDD and VSS?

While the absolute maximum potential difference is 18 V, the datasheet recommends a maximum difference of 15 V between VDD and VSS for optimal parameter performance.

How does the MC14066B compare to the MC14016B?

The MC14066B is designed to be pin-for-pin compatible with the MC14016B but features significantly lower ON resistance.
