FSA4157AL6X

Overview

The FSA4157AL6X is a discontinued Single Pole/Double Throw (SPDT) analog switch fabricated with sub-micron CMOS technology. It operates within a supply voltage range of 2.7 V to 5.5 V and features an ultra-low maximum on-resistance of 1.15 Ohms at 4.5 V VCC. The device supports a maximum DC switch current of 200 mA and includes break-before-make enable circuitry. It utilizes a MicroPak-6 package (SIP6, Case 127EB) for surface-mount installation.

Feature Summary

Ultra-low on-resistance performance
Break-before-make switching capability
TTL-compatible control input

Applications

Mobile handset signal routing
Baseband processor interface circuits
Portable electronic equipment

Procurement Notes

This component has been officially discontinued by the manufacturer and is not recommended for new designs. Verify availability through secondary market channels or contact the manufacturer directly for further information regarding obsolete status.

Selection Notes

Select this part only for legacy system maintenance where the specific MicroPak-6 footprint and SPDT configuration are required. Ensure the design accommodates the 2.7 V minimum supply voltage constraint and verify that the 1.15 Ohm on-resistance meets the signal integrity requirements.

Part Context

The FSA4157AL6X belongs to the FSA4157A series of low-voltage analog switches. It shares functional similarities with the FSA4157 but differs in its minimum operating voltage threshold. Both variants utilize the same MicroPak-6 package and offer comparable switching speeds and on-resistance characteristics.

Replacement Considerations

The datasheet explicitly states these devices are discontinued and recommends contacting the manufacturer for alternatives. No specific replacement part numbers are provided in the official documentation.
