MC14066BDTEL

Overview

The MC14066BDTEL is a quad analog switch manufactured by onsemi, featuring four independent bilateral switches capable of controlling digital or analog signals. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The device utilizes a TSSOP-14 surface-mount package. Key electrical specifications include a maximum on-resistance of 280 ohms, a maximum propagation delay of 120 ns, and a maximum turn-off time of 80 ns.

Feature Summary

• Triple diode protection provided on all control inputs for enhanced robustness
• Linearized transfer characteristics ensure consistent signal transmission performance
• Pin-for-pin compatible with legacy CD4016 and MC14016B designs

Applications

• Signal gating and switching applications
• Chopper stabilization circuits
• Modulator and demodulator implementations
• CMOS logic circuit integration

Procurement Notes

Verify the specific suffix BDTEL against official onsemi documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the ordering number with the manufacturer's current datasheet revision to validate active status and any potential pinout or parameter updates before finalizing procurement.

Selection Notes

Select this component when low on-resistance and wide supply voltage compatibility are required for analog signal routing. It serves as a direct replacement for older CMOS switches like the CD4016. Consider the HC4066 series if lower on-resistance and higher speed are necessary, as the standard MC14066B offers moderate performance suitable for general-purpose switching tasks.

Part Context

This part belongs to the MC14066B family of quad analog switches produced by onsemi. It is designed for applications requiring reliable bilateral switching of both digital and analog waveforms. The device is widely used in communication systems and signal processing equipment where linear transmission characteristics and broad operational voltage ranges are critical for system stability.

Replacement Considerations

Publicly confirmed substitute part numbers include CD4066BM96, CD4066BMT, CD4066BQDRQ1, and CD74HC4066M from Texas Instruments. These alternatives offer similar functionality but may differ in specific electrical parameters or package dimensions.
