FSA4157AP6

Overview

The FSA4157AP6 is a low-voltage 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 on-resistance maximum of 1.15 Ω at 4.5 V VCC. The device supports fast switching speeds with turn-on times as low as 35 ns and turn-off times down to 15 ns. Designed for break-before-make operation, it includes over-voltage tolerant TTL-compatible control circuitry. The component is available in a space-saving 6-lead SC-88 package.

Feature Summary

Ultra-low on-resistance performance
Low quiescent current when control voltage is lower than supply
Break-before-make enable circuitry

Applications

Mobile handset applications
Direct interface with baseband processor general purpose I/Os

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and shipping configuration. Confirm RoHS compliance status and check for any product discontinuance notifications or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this model when a low-voltage SPDT switch is required with minimal signal distortion. Ensure the application control logic remains within the specified input voltage limits. Verify that the operating temperature range meets the system requirements.

Part Context

This component belongs to the FSA4157 series of high-performance analog switches. The 'A' designation indicates specific electrical characteristics regarding quiescent current behavior relative to the control input voltage compared to the standard variant.
