MC14066BDTR2

Overview

The MC14066BDTR2 is a quad analog switch manufactured by onsemi, housed in a TSSOP-14 package. It operates within a supply voltage range of 3.0 V to 18 V 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 300 Ohms at 15 V supply. Propagation delay times are specified up to 40 ns, while control-to-output switching times reach 120 ns. The component includes triple diode protection on all control inputs and offers linearized transfer characteristics.

Feature Summary

• Quad bilateral switch configuration for independent signal gating
• Triple diode protection integrated on all control inputs
• Linearized transfer characteristics for analog signal handling
• Pin-for-pin compatibility with legacy CD4016 and MC14016B devices

Applications

• Signal gating circuits
• Chopper stabilization systems
• Modulator and demodulator implementations
• CMOS logic implementation

Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the tape and reel packaging format containing 2500 units per reel. Confirm the TSSOP-14 package designation matches the required board layout constraints. Ensure the component revision aligns with current manufacturing standards as defined by the manufacturer's documentation.

Selection Notes

Select this component when pin-compatible replacement for older CMOS analog switches is required. Consider the lower ON resistance compared to standard MC14016B variants. Evaluate the 3V to 18V operating range against system power supplies. Verify thermal dissipation requirements do not exceed the 500 mW package limit under maximum load conditions.

Part Context

This part belongs to the MC14066B series of quad analog switches produced by onsemi. It serves as a direct functional equivalent to industry-standard CD4016 devices but provides improved electrical performance regarding ON resistance. The series is designed for general-purpose analog signal routing in digital and mixed-signal environments.

Replacement Considerations

FAQ

What is the maximum recommended supply voltage difference?

While the absolute maximum rating is 18.0 volts, the datasheet recommends a maximum difference of 15 volts between VDD and VSS for optimal parameter specification.

How does the MC14066B compare to the MC14016B?

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