SN74AVCH8T245PWR is an integrated circuit chip developed by Texas Instruments that performs the function of a level shifting translator in data transfer applications. It provides the connection between two different voltage levels, making the data compatible from one device to the other. It belongs to the category of logic-translators and level-shifters.

This chip can perform eight-bit level shifting for unidirectional applications and has an AUTO-SENSE system to sense the direction of data with no need for external control signals. This chip is found in a variety of components in the fields of automotive, communications, medical, industrial and military.

The SN74AVCH8T245PWR is an ideal choice for switching between low voltage (1.2 V-2.7 V) and ultra-low voltage (1.2 V) devices. Such devices are used in a variety of automotive applications due to their ability to perform level shifting for low voltage signals in a variety of line lengths and twisted wire configurations. It is also suited for the switching between devices with varying supply voltages of 2.8 V - 5 V, 6 V - 12 V, and 9 V - 15 V. This allows for improved noise immunity and improved EMC (electromagnetic compatibility) performance.

The chip consists of two blocks: the Translator and the Level Shifter. The Translator is primarily responsible for decoding the data and converting the data from one voltage level to another – the outputs of the translator are referred to as the “Differential Outputs”. The Level Shifter then shifts the data between the various voltage levels. It contains an internal latch, a low voltage output driver, an enable input, and a control input. The enable input is used to turn on and off the driver while the control input is used to enable or disable the chip’s level shifting and/or voltage translation capabilities.

The chip is constructed using TSMC’s advanced logic gates and pass transistors, which ensures low on-resistance levels for low voltage drops and low power consumption. The chip is also designed to be EMI (electromagnetic interference) immune and capable of passing emissions tests. This helps ensure that any application using the SN74AVCH8T245PWR will not interfere with any other nearby electronic equipment.

The SN74AVCH8T245PWR is an extremely versatile chip, capable of being used in a variety of data transfer applications. Its low power and noise immunity, combined with its high speed and wide voltage range make it an attractive choice for many automotive and industrial applications.
