The MAX4744HELB from Maxim Integrated is a high-performance, 4-channel, 2:1 analog multiplexer/switch designed for precision applications that require low-voltage operation. This device is ideal for battery-powered equipment due to its low power consumption and wide single-supply voltage range of 1.8V to 5.5V, making it versatile across various applications.
Featuring a max on-resistance of just 4Ω and a channel-to-channel on-resistance matching of less than 0.5Ω, the MAX4744HELB ensures signal integrity by minimizing signal attenuation and providing excellent linearity. The low on-resistance flatness of 0.5Ω across the specified signal range further ensures minimal distortion, making it suitable for audio and video signal routing.
The device is equipped with break-before-make switching, which prevents momentary shorting of signals during the transition from one channel to another. This feature is critical for applications where signal integrity is paramount. Additionally, the MAX4744HELB has an ESD tolerance of ±15kV Human Body Model (HBM), providing robust protection against electrostatic discharges.
Maxim Integrated has designed the MAX4744HELB with a digital logic interface that is compatible with low-voltage CMOS signals, making it easily interfaced with modern microcontrollers and digital logic systems. The device also features a low crosstalk between switches and off-isolation, ensuring minimal interference between channels.
The MAX4744HELB is available in a compact 16-pin QFN package, which is suitable for space-constrained applications. Its operating temperature range of -40°C to +85°C allows for use in a variety of environments, from industrial to commercial settings.
With its combination of low-voltage operation, low on-resistance, and high ESD protection, the MAX4744HELB is an excellent choice for designers who require a reliable and efficient multiplexer/switch for their analog or digital signal routing needs.
