FSA1156L6X

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers Applications

• Portable consumer electronics
• Battery-powered equipment
• Communication devices

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
