Overview
The FSAT66L6X is a low-voltage single SPST normally open analog switch IC manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 7 Ohms. The device supports a maximum power dissipation of 200 mW with a maximum supply current of 10 uA. Switching performance includes a maximum turn-on time of 4.5 ns and a maximum turn-off time of 5.5 ns. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a MicroPak-6 surface-mount package.
Feature Summary
- Single-channel SPST configuration for signal routing
- Low voltage operation compatible with modern digital systems
- Fast switching speeds suitable for high-frequency applications
Applications
- Portable consumer electronics requiring low power consumption
- Battery-powered devices utilizing low voltage supplies
- Signal path selection in communication equipment
Procurement Notes
Verify the manufacturer designation as onsemi, resulting from corporate integration, when sourcing this component. Confirm the specific ordering suffix matches the required tape and reel or cut tape packaging format. Ensure compliance with RoHS directives and check for any product change notices related to the Fairchild Semiconductor legacy part number before finalizing procurement orders.
Selection Notes
Select this component for designs requiring a single-pole single-throw switch with low on-resistance and fast transition times. The MicroPak-6 package offers a compact footprint for space-constrained layouts. Verify that the system supply voltage remains within the 1.65 V to 5.5 V operational limits to ensure proper functionality and avoid exceeding the maximum power dissipation rating under all load conditions.
Part Context
This component belongs to the family of low-voltage analog switches originally developed by Fairchild Semiconductor. Following the acquisition and integration into onsemi, the part number remains valid but may be subject to updated nomenclature standards. It serves as a discrete solution for signal switching in portable and battery-operated applications where size and power efficiency are critical design parameters.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications against alternative single SPST switches if direct replacement is necessary.
