The SN74AUP1T98DSFR is a voltage levels single-supply voltage translator manufactured by Texas Instruments, Inc. It is a low-power, Bidirectional, logic-level translation device, which provides the capability to translate a digital signal between two voltage levels that are not compatible. The translator works by shifting the input signal up or down to match the desired output. It is specifically designed to enable 3.3V devices to communicate with higher voltage systems like 5V and 12V. It features an enable pin, which controls the flow of data and can be used to reduce power consumption. This part is housed in a small, low profile package with an extended temperature range and low power consumption. It is an ideal choice for applications such as I2C, SPI and UART-level translators.
