MAX4980ETA - High-Speed USB 2.0 Switch from Maxim Integrated

The MAX4980ETA is a high-performance, high-speed USB 2.0 analog switch with low on-capacitance (C_ON) and low on-resistance (R_ON), making it an ideal choice for USB 2.0 applications. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this switch is designed to operate at a single supply voltage of 3.0V to 3.6V, which is typical for USB applications.

Featuring a bidirectional design, the MAX4980ETA can switch USB 2.0 signals with minimal signal distortion due to its low R_ON. This ensures that the integrity of high-speed data is maintained, which is critical for maintaining USB 2.0's 480Mbps data rate. The low C_ON helps to reduce signal attenuation, further ensuring the quality of data transmission through the switch.

With a bandwidth greater than 720MHz, the MAX4980ETA is more than capable of handling the frequency requirements of USB 2.0 signaling. Its extended temperature range of -40°C to +85°C makes it suitable for use in a variety of environments, from consumer electronics to industrial applications.

The MAX4980ETA comes in a small, 8-pin TDFN package, making it space-efficient for design in compact electronic devices such as smartphones, tablets, and laptops. Moreover, it has built-in ESD protection circuitry, which provides ±15kV Air Gap and ±8kV Contact discharge protection as per the IEC 61000-4-2 standard, safeguarding the device from potential damage caused by electrostatic discharges.

This USB 2.0 switch also includes additional features such as a low-power shutdown mode and an active-low enable input, which allows the device to be placed into a high-impedance state, reducing power consumption when not in active use.

In summary, the MAX4980ETA from Maxim Integrated is a robust and reliable solution for applications requiring the switching of high-speed USB 2.0 signals with minimal signal degradation. Its small form factor, high-performance specifications, and added protective features make it an excellent choice for designers looking to optimize their USB-enabled devices.
