The MAX202CDW is a two channel level shifter that is designed to withstand very high levels of stress from thermal, mechanical, and electrical sources. It features two channels with both input and output stages that are rated up to 25.2 V. With its high PFET/N-FET logic level conversion capability, it is the perfect choice for a variety of applications that need a high degree of electrical isolation from their environment. The MAX202CDW features a wide range of protection features and wide temperature range of operation. It is suitable for interfacing digital logic systems with different logic voltages levels.

The MAX202CDW is commonly used in automotive, audio/video, telecom, and industrial applications. Its low power consumption and wide temperature range make it particularly well-suited for automotive environments. It can be used in automotive networks, such as CANbus and LINbus, as well as SENT, SAE J1939, and ISO 11898. It is also used to provide interface between the host and the edge nodes in distributed control systems. Additionally, the MAX202CDW is used in automotive audio/video systems, such as vehicle antenna systems and video signal switching. In industrial applications, it can be used as a direct digital signal interface between programmable logic controllers (PLCs) and other digital systems.

The MAX202CDW works by providing two channels of bi-directional level shifting. Each channel has both an input and an output stage. The input stage is designed to drive a low-Vth FET, while the output stage drives a higher-Vth FET. When the output stage is driven, the input stage is disabled, so there is no chance of cross-coupled interference. The output stage is driven by a PNP logic level FET, while the input stage is driven by an NPN logic level FET. Both FETs are independently controlled and the PNP FET has an adjustable threshold for the on-state voltage.

The level shifters of the MAX202CDW are designed to operate over wide temperature ranges and can withstand very high stresses from thermal, mechanical, and electrical sources. The internal power supply of the MAX202CDW is designed with a wide operating range from 5.5 to 25.2 V. This provides a large margin for interfacing with a variety of logic levels. The device can handle currents up to ± 15mA and has a slew rate of 1.5V/us. Additionally, the device is protected against over-voltage, over- temperature, and reverse polarity.

In summary, the MAX202CDW is a two channel level shifter that can withstand a variety of stress sources and is suitable for interfacing with digital logic systems with different logic voltages. Its wide operating voltage range, fast slew rate, and protection features make it well-suited for use in a wide variety of applications, including automotive, audio/video, telecom, and industrial applications.
