Overview
The FSAT66L6X is a low voltage single pole/single throw (SPST) normally open analog switch fabricated on a sub-micron CMOS process. It features a TTL compatible control input and operates within a broad supply voltage range of 1.65V to 5.5V. The device provides rail-to-rail signal handling with an on-resistance of 5Ω at VCC=3.0V. Key electrical parameters include a propagation delay of 0.7ns typical at 3.0V, off-isolation of -50dB at 10MHz, and a -3dB bandwidth exceeding 250MHz. It is housed in a 6-lead MicroPak package.
Feature Summary
- Space-saving MicroPak leadless package
- Broad operating voltage range from 1.65V to 5.5V
- TTL compatible control input levels
- Rail-to-rail signal handling capability
Applications
- Portable battery-powered equipment
- LCD panel bias voltage switching
- Signal routing in communication systems
Procurement Notes
Verify the specific ordering suffix L6X corresponds to the 6-lead MicroPak package configuration. Confirm that the component is supplied in tape and reel format containing 5,000 units per carrier. Ensure compatibility with the specified surface mount thermal requirements for the MicroPak footprint during assembly.
Selection Notes
Select this component when a compact SPST analog switch is required for low-voltage applications. The device is suitable for designs needing rail-to-rail signal transmission and minimal propagation delay. Consider the 5Ω on-resistance and charge injection characteristics for precision signal path requirements.
Part Context
The FSAT66 series includes variants such as the M5X and P5X, which utilize SOT23 and SC70 packages respectively. The L6X variant specifically denotes the 6-lead MicroPak form factor. All variants share identical internal circuitry and electrical specifications, differing only in physical packaging dimensions and mounting style.
Replacement Considerations
Direct replacements must match the 6-lead MicroPak package and maintain equivalent electrical performance. Verify that alternative components support the 1.65V minimum supply voltage and provide comparable on-resistance and bandwidth specifications.
