Frequently Asked Questions
What is the bandwidth and on-resistance of the SN74AUC1G66DCKRE4?
The SN74AUC1G66DCKRE4 provides a nominal bandwidth of 500MHz and a maximum on-state resistance of 20Ω. The 55dB off-state isolation ensures minimal signal leakage when the switch is open, making it appropriate for both low-frequency analog and high-frequency RF signal switching applications.
What supply voltage range does the SN74AUC1G66DCKRE4 support?
As an AUC-family device, the SN74AUC1G66DCKRE4 operates from 0.8V to 2.7V supply voltage, targeting ultra-low-voltage portable and IoT applications. This low supply range enables direct integration with modern sub-1V processor cores and 1.8V or 2.5V peripheral interfaces without voltage translation.
What is the switch configuration of the SN74AUC1G66DCKRE4?
The SN74AUC1G66DCKRE4 implements a single-pole single-throw (SPST) bilateral analog switch with one channel. Being bilateral means the signal can flow in either direction through the switch, allowing it to be used for both signal routing and bidirectional bus switching in analog and mixed-signal circuit designs.
What package does the SN74AUC1G66DCKRE4 use and is it RoHS compliant?
The device is packaged in a SOT23-5 (5-pin SC-70 compatible) package, which is extremely small and suitable for space-critical applications. The E4 suffix confirms that it is fully RoHS and REACH compliant with a lead-free, halogen-free material set meeting current environmental regulations.
What are typical applications for the SN74AUC1G66DCKRE4?
This analog switch is commonly used in battery-powered portable electronics, audio signal routing, sensor interface multiplexing, and communication bus switching. Its high bandwidth of 500MHz and low on-resistance also make it suitable for video signal switching and RF path selection in handheld wireless devices and wearable electronics.
