Overview
The NLAS4717FCT1 is a dual independent Single Pole Double Throw (SPDT) analog switch fabricated in sub-micron silicon gate CMOS technology. It features two low RDS(on) channels of 4.5 ohms at 3.0 V supply voltage. The device operates within a wide low voltage range from 1.8 V to 5.5 V and provides high bandwidth exceeding 40 MHz. Key electrical characteristics include guaranteed Break-Before-Make switching, ultra-low charge injection of 6.0 pC maximum, and low standby current of 1.0 nA maximum at 25°C. The component includes overvoltage tolerance on control pins and meets JEDEC latchup specifications.
Feature Summary
- Dual independent SPDT analog switches with guaranteed Break-Before-Make operation
- High bandwidth exceeding 40 MHz for signal integrity
- Ultra-low charge injection and low standby current
- Overvoltage tolerance on digital select input pins
Applications
- Cell Phones

Procurement Notes
Verify the specific package type matches the design requirements, as this part number corresponds to the Flip-Chip-10 configuration. Confirm that the ordering suffix indicates lead-free compliance if environmental regulations apply to the assembly process. Ensure the supply voltage range aligns with the system's power architecture before finalizing procurement.
Selection Notes
Select this component when a compact dual SPDT switch is required for portable electronics. The Flip-Chip-10 package offers a small footprint suitable for space-constrained designs. Verify that the operating voltage range of 1.8 V to 5.5 V covers the application's signal levels. Consider the 4.5 ohm on-resistance at 3.0 V for signal loss calculations in the circuit design.
Part Context
This device belongs to the NLAS4717 family of high-bandwidth analog switches manufactured by onsemi. It is designed for applications requiring low distortion and fast switching speeds in portable consumer electronics. The product line emphasizes miniaturization and power efficiency through advanced CMOS fabrication processes.
Replacement Considerations
The datasheet explicitly states pin-to-pin compatibility with the MAX4717. Designers may consider this alternative if sourcing constraints exist, provided the MAX4717 specifications meet the application's performance requirements.
