FSA4157L6X

Overview

The FSA4157L6X is a discontinued Single Pole/Double Throw (SPDT) analog switch fabricated with sub-micron CMOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance (RON) of 1.15 Ω at 4.5 V VCC. The device supports a maximum switch current of 200 mA and includes break-before-make enable circuitry. It utilizes a MicroPak-6 package (SIP6, Case 127EB) and functions over an operating temperature range of -40°C to +85°C.

Feature Summary

Ultra-low on-resistance of 1.15 Ω maximum at 4.5 V VCC
Break-before-make operation capability for signal integrity
TTL-compatible control input interface
Space-saving 6-lead MicroPak package

Applications

Mobile handset signal routing
Baseband processor general-purpose I/O interfacing
Low-voltage analog signal switching

Procurement Notes

This component is officially discontinued by the manufacturer and is not recommended for new designs. Verification of availability requires direct contact with onsemi representatives or authorized distributors, as standard retail channels may no longer stock this specific part number.

Selection Notes

Engineers should evaluate alternative SPDT analog switches from the current portfolio due to the discontinuation status. Considerations must include matching the required supply voltage range, on-resistance specifications, and package footprint compatibility during the transition to a replacement component.

Part Context

The FSA4157L6X belongs to the FSA4157 series of low-voltage analog switches produced by onsemi. This series was designed for portable applications requiring high performance in small form factors. The L6X suffix specifically denotes the MicroPak-6 packaging configuration.

Replacement Considerations

Refer to the official datasheet ordering information table for confirmed substitute part numbers. Contact onsemi sales representatives for current recommendations regarding equivalent active components.
