MAX4854HLETE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4854HLETE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features high-bandwidth signal handling capabilities and over-rail protection, allowing it to pass signals exceeding the supply voltage rails. The device operates with a single +3V to +12V power supply or dual ±1.5V to ±6V supplies. It offers low on-resistance of 7Ω and supports continuous current up to 200mA per channel. Packaged in an 8-pin TSSOP format, it is designed for applications requiring robust signal switching with extended voltage tolerance.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Quad SPST configuration providing four independent signal paths
• Over-rail signal handling protects against input voltages beyond supply limits
• High bandwidth suitable for video and RF signal routing
• Low on-resistance ensures minimal signal attenuation

Analog Switches, Multiplexers, Demultiplexers Applications

• Video signal switching and routing
• RF signal path control
• Data acquisition systems
• Communication equipment signal gating

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix HLETE corresponds to the tape-and-reel packaging variant when ordering. Confirm the manufacturer designation as Analog Devices Inc. following the Maxim Integrated acquisition. Ensure compatibility with standard 8-pin TSSOP footprints during PCB layout verification.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multi-channel switching with over-voltage tolerance is required. Compare on-resistance specifications against other quad switches if signal integrity at high frequencies is critical. Verify that the 200mA continuous current rating meets the load requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX485x family of analog switches from Maxim Integrated, now part of Analog Devices. It serves as a high-performance alternative to standard CMOS switches, specifically engineered for applications where signal lines may exceed the device's power supply rails without causing damage or latch-up.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Potential substitutes include the MAX4854HETE and MAX4854H. Verify pinout compatibility and ensure the replacement package matches the required footprint. Check datasheets for equivalent on-resistance and breakdown voltage specifications.
