The MAX222IDWRG4 is a highly integrated, high-performance, level-shifting, non-inverting, voltage translator that integrates dual slew-rate control, in-rush current control, thermal shutdown and low-audio-noise charge pumps. It is designed and manufactured with state-of-the-art technologies to provide direct interfacing of two voltage levels in various applications.

The MAX222IDWRG4 can connect between two logic levels of devices and circuits without the need for high-voltage power supplies. It is particularly well suited for interfacing between a 3.3V and 5V logic, such as when a 3.3V output device needs to drive a 5V input device. In addition, it features a built-in slew rate control for improved EMI and noise immunity.

The MAX222IDWRG4 is designed for a wide variety of interface applications, including, but not limited to, bridging logic interfaces, logic level-shifting, chipsets, and transceivers. It provides direct interfacing between 5V and 3.3V logic with data rates up to 33 megahertz. The logic-high level threshold voltage is externally adjustable allowing signals with levels to be matched to the logic levels of the devices connected to it. Its wide common-mode range and adjustable threshold levels make it suitable for use in 3.3V, 5V, and mixed-signal systems.

The MAX222IDWRG4 functions with a steady 3.3V to 5V supply voltage, with built-in slew rate control to help reduce electromagnetic interference (EMI) and noise. It also provides hysteresis at the logic levels to ensure high performance in noisy environments. It has an automatic current limit feature that limits inrush current during turn-on, which conserves power and helps protect the supply wiring.

The device has an integrated thermal shutoff feature that shuts off the translator when the junction temperature exceeds the thermal set point, and is designed to restart automatically when the temperature drops below a predetermined level. It also incorporates a monolithic low-noise oscillator to protect from long stretches of pulses or pulses of very short duty cycles.

The MAX222IDWRG4 is designed for a wide variety of interface applications, including, but not limited to, bridging between two logic interfaces, level-shifting, chipsets, and transceivers. It is available in the TSSOP-14 and HTSSOP-14 packages, and comes in temperature grades of -40 degrees to 85 degrees Celsius, and 0 degrees to 125 degrees Celsius. It has a maximum power dissipation of 1.25 W and a maximum current output of 30 mA.

In its simplest implementation, the MAX222IDWRG4 can be used as an interface between two different logic voltages. In more complex applications, the device can be used for matched driver-receiver systems, such as for a ground-isolated interface between two separate systems. It is also suitable for interfacing between a microprocessor or gate array and logic gate functions.

The MAX222IDWRG4 can operate in either its standard or high-speed modes. In the high speed mode, the MAX222IDWRG4 has a maximum data rate of 33 megahertz and a maximum output current of 30 mA. It can also be used in applications requiring the synchronous conversion of two logic levels, such as with DSPs, microcontrollers and FPGAs.

To sum up, the MAX222IDWRG4 is a highly integrated, high-performance, level-shifting, non-inverting, voltage translator that integrates dual slew-rate control, in-rush current control, thermal shutdown and low-audio-noise charge pumps. It is designed for a wide variety of interface applications, including, but not limited to, bridging between two logic interfaces, chipsets, level-shifting, and transceivers. It provides direct interfacing between 5V and 3.3V logic with data rates up to 33 megahertz, making it ideal for use in 3.3V, 5V and mixed-signal systems.
