MAX4617EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4617EUE+T is a high-speed, low-voltage CMOS analog multiplexer configured as an 8-channel switch. It operates on a single +2V to +5.5V supply and handles rail-to-rail analog signals. The device features fast switching times with a maximum turn-on time of 15ns and turn-off time of 10ns at +25°C. On-resistance is guaranteed at 10Ω max (+5V) and 20Ω max (+3V). Off-leakage current is typically 1nA at +25°C. Digital inputs are TTL/CMOS compatible. It is housed in a 16-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C) compared to the commercial 'C' variant. Confirm the '+T' designation corresponds to tape-and-reel packaging rather than cut tape or tube formats. Ensure the component source matches Analog Devices specifications to avoid counterfeit parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when pin compatibility with legacy 74HC4051 designs is required alongside superior electrical performance. Consider the MAX4617 over standard logic switches if lower on-resistance variation and higher off-isolation are critical. Evaluate power consumption requirements against the typical 1µA supply current at +5V.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4617 belongs to the MAX4617/MAX4618/MAX4619 family of high-speed, low-voltage CMOS analog switches. While the MAX4617 provides a single 8:1 multiplexer, the MAX4618 offers two 4:1 multiplexers, and the MAX4619 contains three SPDT switches. All share identical pinouts and core architecture.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4581, MAX4582, and MAX4583. Standard logic equivalents such as the 74HC4051, 74HC4052, and 74HC4053 can be used but may differ electrically in resistance and leakage characteristics.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4617 handle analog signals exceeding the VCC or GND rails?

Internal reverse ESD-protection diodes clamp any analog signal that exceeds VCC or GND by approximately 0.3V. Designers must limit forward-diode current to the maximum rating to prevent damage.

What is the break-before-make time for the MAX4617?

The break-before-make time is typically 1.5ns at +25°C, ensuring that one channel turns off before another turns on during switching transitions.

Is the MAX4617 compatible with both TTL and CMOS logic levels?

Yes, the digital inputs have logic thresholds of 0.8V to 2.4V, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.
