MC14066RFL2

Overview

The MC14066RFL2 is a quad analog switch IC from onsemi, operating within a supply voltage range of 3 V to 18 V. It features four independent channels in a 1x1 configuration, housed in an SOIC-14 package. Key electrical parameters include a maximum on-resistance of 280 Ohms and a bandwidth of 65 MHz. The device supports single-supply operation with a maximum switch voltage of 15 V and power dissipation of 500 mW. Timing characteristics specify a maximum propagation delay of 40 ns, turn-on time of 120 ns, and turn-off time of 80 ns. It functions reliably across an extended temperature range from -55°C to +125°C.

Feature Summary

• Provides four independent analog signal paths for switching applications
• Operates with a wide single-supply voltage range up to 18 V
• Supports high-frequency signal transmission with 65 MHz bandwidth
• Designed for reliable performance in extended industrial temperature environments

Applications

• Signal routing in multiplexer circuits
• Analog signal switching in data acquisition systems
• Audio and video signal path selection
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific suffix 'RFL2' against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the required package variant and environmental compliance specifications. Cross-reference the manufacturer's latest datasheet for any pinout or electrical parameter updates prior to procurement.

Selection Notes

Select this component when a quad analog switch with low on-resistance and wide supply voltage compatibility is required. Consider the SOIC-14 package for surface-mount assembly constraints. Evaluate the 280 Ohm on-resistance limit against signal integrity requirements. Confirm that the 65 MHz bandwidth meets the frequency demands of the target application signals.

Part Context

The MC14066 series belongs to onsemi's standard logic family of analog switches. This specific model represents a quad configuration variant designed for general-purpose signal routing. It complements other members of the family by offering multiple isolated channels in a compact footprint, suitable for integrating into larger mixed-signal systems requiring flexible connectivity.

Replacement Considerations

Check for direct cross-reference part numbers such as MC14066BDR2G which shares similar quad analog switch functionality. Verify pin compatibility and electrical specifications before substitution. Ensure alternative components meet the same voltage and temperature ratings.
