FSA5157L6X-S

Overview

The FSA5157L6X-S is a low on-resistance, low-power Single Pole Double Throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 4.3 V and features a typical on resistance of 0.4 Ω at +2.7 V supply. The device supports continuous current handling up to 350 mA under a 3.3 V supply and includes break-before-make functionality with bi-directional operation. It is housed in a SIP6 package measuring 1.45 x 1.0 mm.

Feature Summary

Ultra-low on resistance for high signal integrity
Sub-nanoampere quiescent current consumption
Bi-directional data ports with break-before-make switching
Compatible with 1.8 V CMOS control logic

Applications

Cellular phones
Personal Digital Assistants (PDA)
Portable media players

Procurement Notes

Verify the specific ordering suffix 'S' against the official datasheet, as standard listings typically reference 'FSA5157L6X'. Confirm the package type matches the SIP6 outline and ensure RoHS compliance requirements are met for the target application environment.

Selection Notes

Select this component for battery-powered designs requiring low power dissipation and minimal signal distortion. Ensure the control input voltage remains compatible with the 1.8 V CMOS logic levels specified. Verify that the operating temperature range of -40°C to +85°C aligns with system constraints.

Part Context

This part belongs to the FSA5157 series of low-voltage analog switches. It serves as an alternative to higher voltage or higher power devices, specifically optimized for portable consumer electronics where space and energy efficiency are critical design parameters.
