Maxim Integrated's MAX3393EEUD+T - Bidirectional Voltage-Level Translator

The MAX3393EEUD+T is a versatile, high-performance bidirectional voltage-level translator from Maxim Integrated, designed to provide seamless voltage level translation between low-voltage digital signal levels and higher-voltage digital signal levels. This device is particularly well-suited for applications where two different voltage domains need to interface with each other, such as between a microcontroller operating at a lower voltage and peripheral devices that require a higher voltage.

With its dual-supply voltage operation, the MAX3393EEUD+T can translate signals between two different voltage levels ranging from 1.2V to 3.6V on the V<sub>L side and 1.65V to 5.5V on the V<sub>CC side. This broad range makes it compatible with most of the common logic levels used in today's digital systems, including 1.8V, 2.5V, 3.3V, and 5V logic.

The device features a low on-resistance (R<sub>ON) of the switch, which allows for high-speed operation with minimal signal distortion, making it ideal for high-speed data lines that require fast signal propagation times. Furthermore, the MAX3393EEUD+T does not require a direction control signal, as the direction of data flow is determined automatically, simplifying the design and reducing the control line overhead.

Enclosed in a 14-pin TSSOP package, the MAX3393EEUD+T is compact and suitable for space-constrained applications. It is also specified for the extended -40°C to +85°C temperature range, which makes it reliable for use in industrial and automotive environments where temperature extremes are common.

Key features of the MAX3393EEUD+T include:

• Automatic bidirectional voltage translation without direction pin
• Dual-supply voltage operation (V<sub>L: 1.2V to 3.6V, V<sub>CC: 1.65V to 5.5V)
• Low on-resistance (R<sub>ON)
• High-speed performance
• Extended temperature range (-40°C to +85°C)
• 14-pin TSSOP package for compact design

Whether it's for interfacing microcontrollers with peripheral devices, or for data communication across different voltage domains, the MAX3393EEUD+T provides a reliable and efficient solution for voltage-level translation needs.
