MAX13342EEBC-

Drivers, Receivers, Transceivers Overview

The MAX13342EEBC- is a USB-compliant transceiver designed for full-speed (12Mbps) operation per the USB 2.0 specification. It integrates an internal 3.3V regulator, a 1.5kΩ D+ pullup resistor, and ±15kV ESD protection on D+, D-, and VBUS. The device operates with system supply voltages from +2.3V to +3.6V and includes DAT and SE0 interface signals for a 3-wire connection. It features VBUS detection, an enumerate function, and low-power modes consuming less than 45µA. The component is available in a 12-pin UCSP package measuring 2.0mm x 1.5mm.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix requirements for the MAX13342EEBC- variant against official Maxim Integrated documentation. Confirm that the ordering code matches the intended package type and temperature range. Ensure compatibility with the required logic voltage levels and power supply configurations before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX13342E when external series resistors are needed to multiplex multiple USB devices onto a single connector due to its controlled output impedance. Choose this model over the MAX13345E if direct connection to the USB connector without internal series resistors is not required. Ensure the design supports the necessary 3-wire DAT/SE0 interface and low-voltage logic supply ranges.

Drivers, Receivers, Transceivers Part Context

The MAX13342E is part of the MAX13342E/MAX13345E family of 3-wire interface full-speed USB transceivers manufactured by Analog Devices Inc./Maxim Integrated. This family is engineered to minimize area and external components for interfacing low-voltage ASICs to USB ports. The MAX13342E specifically differs from the MAX13345E by lacking internal series resistors, allowing for external impedance matching.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13345E is a functional alternative within the same family but includes internal series resistors for direct USB connector connection. Verify if the application requires the multiplexing capability provided by the MAX13342E's lower output impedance or if the direct drive of the MAX13345E is sufficient.

Drivers, Receivers, Transceivers FAQ

How does the MAX13342E handle USB enumeration?

The device includes an enumerate function that controls the internal 1.5kΩ D+ pullup resistor. Driving the ENUM pin high connects the resistor to indicate full-speed operation, while driving it low disconnects the resistor.

What is the purpose of the DAT and SE0 signals?

DAT and SE0 form a 3-wire interface. DAT carries data on D+/D- when OE is low, while SE0 drives both D+ and D- low when active high. In receive mode, DAT outputs differential receiver data and SE0 indicates when both lines are low.

Can the MAX13342E be used to share a USB connector?

Yes, the MAX13342E has a controlled output impedance that allows the use of external switches to multiplex two different USB devices onto a single USB connector.
