SN74AUP1T57DBVR is a top-of-the-line logic translator, level shifter family from Texas Instruments. It is a low-voltage, high-performance bidirectional level-shifting solution that operates from a single 1.65-V to 3.6-V supply and is designed to support bidirectional level shifting between 1.2 V and 3.3 V. SN74AUP1T57DBVR has three members: SN74AUP1T57DBVR, SN74AUP1T64DBVR, and SN74AUP1T100DBVR. It provides two low-skew, low-capacitive I/O buffers that guarantee powerful noise immunity and low power consumption, making it the ideal choice for applications that require fast level shifting with speed and low power consumption. It is also the perfect solution for voltage-level migration from 1.8 V to 3.3 V.

SN74AUP1T57DBVR is commonly used to extend the reach and versatility of any system that requires both fixed-voltage 3.3 V and 1.2 V output operations. Common uses of this device include USB, LPC bus, SPI/I²C, UART, as well as FPGA/CPLD level-shifting interfacing with memory, analog-to-digital converters, peripheral devices, and other logic devices. It provides the ultimate flexibility and performance for interfacing between logic circuits with different voltage levels, decreasing system complexity. This device is also very popular in high-performance applications that require the highest noise immunity and low power consumption, notably in medical imaging and High-definition video applications.

The SN74AUP1T57DBVR family consists of two high-performance bidirectional translators/level-shifters with two low-skew, low-capacitive I/O buffers. The two buffers are designed to provide good noise immunity and low power consumption in a very small package. The two buffers provide an asynchronous I/O which allows for signal delay that can exceed the supply voltage. The I/O buffer also reduces the propagation delay and allows signal propagation to occur in the same direction without adding switching noise. This makes the SN74AUP1T57DBVR perfect for high speed and low power applications.

The SN74AUP1T57DBVR family is designed to support bidirectional level shifting between 1.2 V and 3.3 V. It has a wide input-voltage range of 1.65 V to 3.6 V and uses an internal charge pump to provide support for low-voltage supply operation. The SN74AUP1T57DBVR typically operates with a supply voltage of 1.2 V and 3.3 V. It features an active-low enable/disable control with VCC-Disabled-level detection which allows for true hot-swap functionality. Additionally, this device features an internal power-on reset and dynamic in-circuit protection against device failure.

The SN74AUP1T57DBVR family provides improved flexibility over other logic-level translators with its 3-state-output feature. It has a push-pull output stage that transitions to a high-impedance state to isolate two sides of the electrical interface when disabled. This allows the two sides to be controlled or powered independently, which simplifies the circuit design, reducing power consumption and ensuring a reliable level-shifting solution.

In short, SN74AUP1T57DBVR is the perfect choice for any system that requires fast level shifting between 1.2 V and 3.3 V. It offers excellent noise immunity, low power consumption, and superior versatility, making it the go-to choice for voltage-level migration. With its active-low enable/disable control and 3-state-output feature, the SN74AUP1T57DBVR is an ideal device for applications that require both performance and flexibility.
