MAX4617CUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4617CUE+T is a high-speed, low-voltage CMOS analog multiplexer configured as an 8-channel to 1-channel switch. It operates on a single +2V to +5.5V supply and supports rail-to-rail analog signals. The device features fast switching times of 15ns turn-on and 10ns turn-off, with a maximum on-resistance of 10Ω at +5V. It offers low off-leakage current (1nA at +25°C), high off-isolation (>93dB), and low crosstalk (<-96dB). The component is housed in a 16-TSSOP package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C rather than the extended industrial range. Ensure the '+ ' suffix confirms lead-free and RoHS compliance status prior to final procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring pin compatibility with standard 74HC series multiplexers while offering superior speed and lower leakage. Consider the single-supply operation range of +2V to +5.5V for low-voltage system integration. Evaluate the 16-TSSOP package constraints against available board space and thermal dissipation requirements for the target environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4617/MAX4618/MAX4619 family of high-speed, low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4617 specifically provides an 8:1 multiplexing configuration, distinguishing it from the dual 4:1 MAX4618 and the triple SPDT MAX4619 variants within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4617EUE+T for extended temperature ranges (-40°C to +85°C) and industry-standard logic gates such as the 74HC4051, 74HC4052, and 74HC4053, though electrical parameters may differ significantly.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4617 handle overvoltage conditions on analog pins?

Internal reverse ESD-protection diodes connect each analog-signal pin to VCC and GND. If an analog signal exceeds VCC or GND, these diodes conduct, clamping the voltage. Designers should limit forward-diode current to the maximum rating or add external blocking diodes for protection.

What is the behavior of the OFF-state switch at high frequencies?

In the OFF state, the switch acts like a capacitor. At frequencies above 20MHz, off-isolation degrades, becoming approximately -50dB at 10MHz in 50Ω systems and worsening by about 20dB per decade as frequency increases due to capacitive coupling.

Are the input and output pins interchangeable?

Yes, the input and output pins are identical and interchangeable. Signals pass equally well in both directions, allowing any pin designated as X_, Y_, or Z_ to function as either an input or output depending on the circuit design.
