CD74HC4066PW Description

The CD74HC4066PW from Texas Instruments is a high-performance quad bilateral switch designed for analog signal switching in a wide range of applications. Housed in a 14-pin TSSOP package, this IC features four independent SPST (Single-Pole, Single-Throw) switches with low on-state resistance (70Ω max) and minimal leakage current (100nA max). It operates over a 2V to 10V supply range, making it compatible with both low-voltage and standard logic systems. With a -3dB bandwidth of 200MHz, it ensures high-speed signal integrity, while its low channel capacitance (5pF) minimizes signal distortion.

CD74HC4066PW Features

• Low On-State Resistance: 70Ω max ensures minimal signal attenuation.
• High Bandwidth: 200MHz supports high-frequency applications.
• Low Leakage Current: 100nA max enhances signal isolation in off-state.
• Wide Supply Range: 2V to 10V for flexibility in mixed-voltage systems.
• Low Channel Capacitance: 5pF reduces crosstalk and distortion.
• Matched Channels: ΔRon of 500mΩ ensures consistent performance across switches.
• Robust Packaging: 14-TSSOP for compact, surface-mount designs.
• Compliance: ROHS3 and REACH unaffected, suitable for environmentally conscious designs.

CD74HC4066PW Applications

• Audio/Video Signal Routing: Ideal for multimedia switches due to high bandwidth and low distortion.
• Data Acquisition Systems: Low leakage and low Ron enable precise sensor signal multiplexing.
• Communication Systems: Used in RF signal switching and modular interfaces.
• Test & Measurement Equipment: High-speed switching for automated test systems.
• Battery-Powered Devices: Low power consumption suits portable electronics.

Conclusion of CD74HC4066PW

The CD74HC4066PW stands out for its balanced performance in speed, power, and signal fidelity, making it a versatile choice for high-frequency analog switching. Its low Ron, high bandwidth, and robust packaging make it superior to generic switches, particularly in precision and high-speed applications. While it is on Last Time Buy status, its reliability and compliance ensure it remains a preferred solution for legacy and new designs requiring low-distortion signal routing.
