LT1039ISW#PBF

LT1039ISW#PBF Application Field and Working Principle

LT1039ISW#PBF is an integrated transceiver, driver, and receiver for level converter applications, designed with field-effect transistors (FET). It is offered in a small 6-lead SOT23 package and is ideal for level shifting, level conversion, and multiplexer applications. Its application fields include communications,networking, automotive, military, and industrial.

The LT1039ISW#PBF transceiver combines a pair of drivers and a pair of receivers into a single, low power device. It provides a 5V or 12V supply voltage range and it can convert logic voltages from as low as 0.8V up to 3.6V, thus suitable for a wide range of applications from standard logic levels to the low-voltage logic used in memory due to its low power consumption.The LT1039ISW#PBF can switch up to 1.25A of current and it requires minimum gate charge for higher efficiency. It also has a low propagation delay for faster switching and input and output ESD protection up to 8kV HBM.

The LT1039ISW#PBF operates by using two FETs as drivers and two FETs as receivers. The FETs are coupled together in an inverting or non-inverting configuration to form a logic level translator. The logic voltage on one side of the device is converted to a different logic voltage on the other side. The drivers dynamically drive the pull-up and pull-down FETs to transfer the logic levels. The FETs are designed to ensure that the output voltage is always within the proper logic voltage levels. The output FETs are always enabled, even when the inputs are floating or disconnected, to protect the output. The LT1039ISW#PBF also has an enable pin so that the output can be disabled when not in use, thus saving power.

In summary, the LT1039ISW#PBF is an optimal solution for signal level shifting and signal conversion. It is offered in a small 6-lead SOT23 package, and it is ideal for applications where wide voltage range, low power consumption and fast switching speeds are needed. It also features ESD protection and an enable pin for better system power optimization.
