The 74HC4066DB/S400 is a high-speed CMOS quad analog switch manufactured by Rochester Electronics. This device contains four independent, bilateral analog switches. It is designed for switching analog or digital signals. Due to Rochester Electronics' sourcing strategy, this part remains available to extend product lifecycles for legacy designs.

Applications:

• Analog signal switching
• Digital signal switching
• Multiplexing and demultiplexing
• Sample-and-hold circuits
• Logic level translation

Features:

• High speed: tpd = 12 ns (typical) at VCC = 5V
• Low power dissipation: ICC = 2 μA (maximum) at TA = 25 °C
• Wide operating voltage range: 2V to 6V
• Low on-resistance: Ron = 70 Ohms (typical) at VCC = 4.5V
• TTL compatible input thresholds

Benefits:

• Enables high-speed signal switching for demanding applications.
• Minimizes power consumption, suitable for battery-powered devices.
• Offers flexibility with a wide operating voltage range.
• Provides minimal signal attenuation with low on-resistance.
• Facilitates easy interfacing with TTL logic circuits.

Additional Details:

The 74HC4066DB/S400 provides a low-impedance path for both analog and digital signals when the switch is enabled. The switch is controlled by a digital input. The device is fully specified for operation from 2V to 6V. The 74HC4066DB/S400 is pin-compatible with the 4066B series but offers significantly improved speed and power consumption. The device is packaged in a small outline integrated circuit (SOIC) package, making it suitable for surface-mount assembly. The switches are bidirectional, allowing signals to pass in either direction. Each of the four switches is independently controllable. The 74HC4066DB/S400 is ideal for a wide variety of applications requiring reliable and high-performance analog or digital signal switching.
