Translators, level shifters, and logic buffers handle different logic levels of the lowest to the highest and vice-versa. They are mainly used for shifting voltage levels in applications when different logic levels are used, such as in digital data communication equipment, interface adapters and other mobile devices. They can also be used in a variety of other applications, such as driving high frequency clock signals in embedded systems, as well as providing robust signal sourcing and general level-shifting functions. One of the most commonly used translators and level shifters is the SN74AVCH4T245PWR.

The SN74AVCH4T245PWR translator and level shifter are an ultra low-power 4-channel transmitter and receiver pair designed to minimize power consumption in mobile applications. It is the first translator and level shifter to use pulse-skipping technology, which reduces power consumption while in standby mode. It is also designed with a 5-pin MicroPack option, which allows easier board layout and design. The device also has built-in surge protection against electrical noise, as well as low-voltage lockout to prevent unintended data latches.

The SN74AVCH4T245PWR is designed to support voltage level translation between 1.2V and 3.3V standards. It has a low logic threshold voltage of 0.4V and support for VCC=1.2V to VCC=3.3V, allowing for level-shifting between i.MX6UL, STM32 and other low-voltage systems. This translator and level shifter is also compatible with a wide variety of clock-driven logic, including TTL and LVTTL, as well as standard I2C and SPI interfaces. It can operate up to 50 MHz and provides one transmitter and one receiver port for each I/O.

The SN74AVCH4T245PWR integrated chip offers a wide range of applications such as sensor interfaces, real-time clock (RTC) battery backup, audio and video interfaces, automotive bus networking, and industrial fieldbus systems. It is suitable for communication interface-based systems, such as SPI, I2C and USB, and supports a variety of logic levels, including LVTTL, TLP, and TTL, making it ideal for interfacing between multiple devices and peripherals with different voltage levels. It is also ideal for providing signal buffering, signal routing, level translation, and data synchronization.

The SN74AVCH4T245PWR translator and level shifter has a maximum output current of 0.32mA and maximum consumption of 76μA when under load, making it one of the lowest power consumption devices available in the market. The device supports a wide range of voltages, from 1.2V to 3.3V, and is available in a small 5-pin MicroPack form factor. It is pin-to-pin compatible, allowing for a simple design transition from existing level-shifting solutions. The device also features built-in 3.3V HCT ESD protection with IEC 61000-4-2 Level 4, making it ideal for automotive, industrial and avionics applications.

The SN74AVCH4T245PWR is an incredibly practical translator and level shifter that offers low power consumption, a wide range of voltages and a small form factor. Its ability to bridge between logic levels and its protection against electrical noise make it an ideal choice for any application that requires a robust level-shifting solution, from sensor interfaces and audio/video interfaces to automotive bus networking, industrial fieldbus systems and more.
