The MAX4581LEEE from Maxim Integrated is a high-performance, low-voltage, CMOS analog multiplexer (mux) featuring a single 8-channel (1-of-8) configuration. It is designed to operate with a single +1.8V to +5.5V supply, making it an excellent choice for battery-powered and portable applications where power efficiency is crucial.

This versatile multiplexer offers low on-resistance (Ron) of less than 100 ohms, which minimizes signal attenuation and ensures excellent analog signal integrity. The on-resistance is matched between channels to within 4 ohms and remains flat over the specified signal range, providing consistent performance across all channels.

The MAX4581LEEE also features fast switching speeds, with tON (turn-on time) and tOFF (turn-off time) typically less than 150ns, allowing for rapid signal routing and high-bandwidth applications. The device's low charge injection further preserves signal quality by reducing the amount of spurious signals introduced during switching events.

For digital interfacing, the mux operates with TTL/CMOS logic levels, making it easy to control via microcontrollers or other digital systems. The MAX4581LEEE's digital inputs have a +0.8V to +2.4V logic threshold, ensuring compatibility with a wide range of control signals.

Additional features include break-before-make switching action, which prevents momentary shorting of channels during transitions. This is particularly important in applications where such shorting could disrupt system functionality or damage components. The device also offers an ESD protection of up to 2000V, safeguarding it against electrostatic discharges during handling and operation.

The MAX4581LEEE is packaged in a compact 16-pin QSOP, which is ideal for space-constrained applications. Its extended temperature range of -40°C to +85°C allows for reliable operation in diverse environmental conditions, making it suitable for industrial, automotive, and communication systems.

In summary, the MAX4581LEEE analog multiplexer from Maxim Integrated is a high-quality, versatile component that delivers reliable performance for a wide range of analog signal switching applications.
