ST2149QTR

The ST2149QTR is a logic translator, level shifter device developed by STMicroelectronics Inc., a world leader in semiconductor technology. This specialized device is designed to provide an interface between two different logic voltage levels, permitting a digital signal to be transmitted across two logic thresholds. By using these specialized devices, logic designers can relieve design problems faced with integrating disparate logic levels in their systems.

The ST2149QTR device has a dual body package with a wide temperature range. This device has a temperature range of -40 to +85 degrees Celsius, allowing it to function in various ambient temperature ranges. Additionally, the ST2149QTR has a low quiescent current of <1uA and a propagation delay of just 0.3 microseconds, giving designers faster and reliable logic switching performance.

The ST2149QTR uses 6 MOSFETs (metal-oxide-semiconductor field-effect transistors) to implement level shifting between the two logic voltage thresholds. Each of the 6 transistors is configured as a source-follower with the source connected to one of the two logic levels and the drain connected to the output voltage. In addition, the start of each MOSFET is controlled by a resistive pull up or pull down circuit with the logic level of each transistor determined by the logic level present at the pull up or pull down circuit.

The ST2149QTR has a wide range of applications in many different industries. This device is ideal for applications requiring level shifting such as low-voltage DC-DC converters and electronic systems that operate over a wide range of temperatures. In addition, this device can also be used in communication systems, sensors, control systems, digital audio, and telecommunications systems.

The ST2149QTR is an invaluable device for designers. Not only does this device facilitate quick and reliable logic level shifting, but it also allows for efficient communication between logic systems with two different logic levels with minimal energy loss. Furthermore, the device’s operating temperature range and its low quiescent current make it an ideal choice for applications that require high-performance level shifting capabilities.
