MAX4780EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4780EUE is a low-voltage, quad 2:1 analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four independent SPDT switches within a single package, offering a maximum on-resistance of 1 ohm and a bandwidth of 123 MHz. The device operates on a single supply voltage ranging from 1.6 V to 4.2 V. Key electrical parameters include a maximum charge injection of 5 pC, an off-state leakage current of 1 nA, and channel-to-channel matching of 100 mΩ. Switching times are specified at a maximum of 25 ns for turn-on and 10 ns for turn-off. The component supports an operating temperature range from -40°C to +85°C and is housed in a 16-TSSOP surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EUE against the manufacturer's official part numbering system to confirm the 16-TSSOP package and industrial temperature grade. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require multiple analog signal paths controlled by a single low-voltage supply. Ensure the input signal amplitude remains within the 1.6 V to 4.2 V supply rails to prevent damage. Verify that the 1 ohm on-resistance meets the system's insertion loss requirements and that the 123 MHz bandwidth is sufficient for the highest frequency components of the signal.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4780 belongs to the Maxim Integrated family of low-voltage analog switches. This series is designed to replace higher-voltage discrete solutions in modern portable electronics. The EUE variant specifically denotes the TSSOP packaging option, distinguishing it from other package types like TQFN available within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the MAX4780 family. Verify that any substitute maintains the 16-TSSOP footprint and matches the 1.6 V minimum supply voltage requirement.
