MAX4618ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4618ESE+T is a high-speed, low-voltage CMOS analog multiplexer IC configured as two independent 4-channel multiplexers. It operates on a single +2V to +5.5V supply and supports rail-to-rail analog signals. The device features fast switching times with a maximum turn-on time of 15ns and turn-off time of 15ns at +25°C. On-resistance is guaranteed at 10Ω max (+5V) and 20Ω max (+3V), with channel matching within 1Ω. Off-leakage current is typically 1nA at +25°C. Digital inputs are TTL/CMOS compatible, and the package is a 16-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and packaging format. The 'E' suffix indicates an industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status based on the '+' designation in the part number. Ensure the narrow SOIC package dimensions match your PCB footprint requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy 74HC series multiplexers is required alongside improved electrical performance. Verify that the single-supply voltage range of +2V to +5.5V aligns with your system power rails. Consider the 10Ω on-resistance at +5V for signal integrity requirements. Ensure the logic input thresholds meet your microcontroller or FPGA output levels for reliable switching control.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4618 is part of the MAX4617/MAX4618/MAX4619 family from Analog Devices (formerly Maxim Integrated). While the MAX4617 provides an 8-channel multiplexer and the MAX4619 offers three SPDT switches, the MAX4618 specifically integrates two 4-channel multiplexers into a single 16-pin package. This configuration allows for efficient signal routing in space-constrained designs requiring multiple independent channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4581, MAX4582, and MAX4583. Legacy standard parts such as the 74HC4051, 74HC4052, and 74HC4053 are also pin-compatible but may differ electrically. Verify that any substitute meets the required on-resistance, leakage, and switching speed specifications for your application.
