FSA2367MTCX

Analog Switches - Special Purpose Overview

The FSA2367MTCX is a triple single-pole double-throw (SPDT) analog switch manufactured by onsemi, housed in a 14-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 4.3 V. The device features three independent channels with a maximum on-resistance of 2 Ohms and supports a DC switch current of 350 mA. Key timing specifications include a maximum turn-on time of 60 ns and a maximum turn-off time of 45 ns. The unit draws a maximum supply current of 500 nA and dissipates up to 2.5 µW of power. It functions reliably within an ambient temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Triple SPDT configuration for multi-channel signal routing
• Low on-resistance for minimal signal attenuation
• Ultra-low power consumption suitable for battery-operated devices
• Break-before-make switching action to prevent signal overlap

Analog Switches - Special Purpose Applications

• Audio signal path switching
• Mobile handset peripheral management
• MP3 player and PMP audio circuits
• Wireless LAN card signal distribution

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific tape-and-reel packaging details match project requirements. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions respect moisture sensitivity level ratings prior to soldering.

Analog Switches - Special Purpose Selection Notes

Select this component when low on-resistance and high isolation are required for audio or data lines. Verify that the operating voltage stays within the 2.7 V to 4.3 V limit. Consider the TSSOP-14 footprint constraints during PCB layout. Evaluate thermal dissipation needs against the specified power rating.

Analog Switches - Special Purpose Part Context

This part belongs to the FSA2367 series of analog switches designed for portable electronics. It complements other multiplexer and crosspoint switch products from onsemi intended for mobile and wireless applications. The series emphasizes low power and small form factors for modern handheld devices.

Analog Switches - Special Purpose Replacement Considerations

The FSA2367BQX serves as a pin-compatible alternative in a DQFN package. Verify package dimensions and thermal characteristics before substitution. Ensure electrical parameters such as on-resistance and voltage limits remain compatible with the existing design.
