CD4066B

The CD4066B from Texas Instruments is a quad bilateral switch designed for transmitting or multiplexing analog or digital signals. It features four independent bilateral switches, providing flexibility in signal routing.

Key electrical characteristics include a typical on-state resistance of 125Ω at 15V operation, which remains relatively constant over the full signal-input range. The device boasts a high on/off output-voltage ratio of 80dB at 10kHz and a linearity of less than 0.5% distortion at 1kHz. With an extremely low off-state switch leakage of 10 pA typical and a high control input impedance of 10¹²Ω typical, it minimizes signal interference and offset currents.

The CD4066B operates over a wide supply voltage range of 3V to 18V, making it suitable for various applications. Its frequency response for switch-on is typically 40MHz. The device is available in multiple package types including PDIP, SOIC, SOP, and TSSOP, all with 14 leads.

Applications for the CD4066B include analog and digital signal switching and multiplexing, such as signal gating, modulators, squelch controls, and analog-to-digital conversions. It is also used in building automation and digital control systems for frequency, impedance, phase, and gain.
