CD4066 IC DIP14 CMOS Switch 4066 CD4066-PDIP-14

Product Overview:

The CD4066B is a CMOS quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is designed to act as a digitally controlled analog switch, allowing high-level signals to be passed through or blocked based on a control input, making it highly useful for signal gating, chopping, modulation, and multiplexing in various electronic circuits.

Core Specifications:

• Manufacturer: Texas Instruments

• Function: CMOS Quad Bilateral Switch

• Operating Voltage: Up to 15V (Digital) or ±7.5V (Peak-to-Peak analog signals)

• Typical On-Resistance: 125Ω (at 15V supply)

• Package Type: Available in various packages including TSSOP-14

Features:

• Flat On-Resistance: Maintains a stable on-resistance across the entire peak-to-peak signal range.

• High Linearity: Exhibits very low distortion (typically less than 0.5% at specific test conditions), making it ideal for high-fidelity signal switching.

• Excellent Isolation: Features a high off-state resistance and low switch-to-switch crosstalk (typical -50dB at 8MHz).

• Control Isolation: The control circuit is electrically isolated from the signal circuit, featuring a very high control input impedance (typically 10¹²Ω).

• Low Leakage: Provides ultra-low off-state leakage current, resulting in high off-state resistance.

Applications:

• Signal Gating/Chopping: Used to periodically interrupt signals in modulation or data acquisition circuits.

• Multiplexing: Essential for routing multiple analog signals to a single output or input (e.g., ADCs).

• Digital Control: Allows microcontrollers or logic circuits to switch analog signal paths dynamically.

• Modulation/Demodulation: Useful in communication circuitry for signal processing tasks.
