Overview
The FSA1156L6X is a single-pole single-throw (SPST) analog switch manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 900 mOhms. The device supports a switching DC current of 200 mA with a maximum power dissipation of 180 mW. Electrical performance includes a maximum turn-on time of 20 ns and a maximum turn-off time of 30 ns. The component functions reliably across an operating temperature range from -40°C to +85°C and draws a maximum supply current of 500 nA.
Feature Summary
- Low on-resistance for efficient signal transmission
- Single-channel SPST configuration
- Low power consumption design
Applications
- Portable consumer electronics
- Battery-powered equipment
- Communication devices
Procurement Notes
Verify the manufacturer designation carefully, as onsemi acquired Fairchild Semiconductor's operations. Confirm the specific suffix 'L6X' matches the required tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm technical specifications have not changed since the original Fairchild release.
Selection Notes
Select this component when a low-voltage, single-channel analog switch is required. The 1.65 V minimum supply voltage makes it suitable for modern portable systems. The 900 mOhm on-resistance is higher than premium switches but adequate for general-purpose signal routing. Verify that the 200 mA current limit meets the load requirements of the application circuit.
Part Context
This part belongs to the FSA1156 series of low-voltage analog switches. The 'L6X' suffix typically denotes the SC-70-6 surface-mount package and reel packaging. The series is designed for applications requiring small form factors and low power operation in mobile and handheld devices.
Replacement Considerations
The FSA1156P6X is a documented variant within the same family, differing primarily in packaging or reel specifications rather than electrical function. Verify pinout compatibility before substitution.
