The LTC4300-2IMS8#PBF is a bi-directional level shifter IC within the Interface - Signal Buffers, Repeaters, Splitters category. It expands a single-supply 2.7V to 5.5V range of logic levels over a wide 0.3V to 2.5V operating range while ensuring no crossover distortion, noise spikes, or current source/sink irregularities. The LTC4300-2IMS8#PBF has low RON of 20Ω, which will effectively control ringing and other structure-borne noise issues that commonly arise in level shifting applications. The chip features two SOT-23-6 / SNOC6Z packages.

The LTC4300-2IMS8#PBF employs a proprietary technique to make the bidirectional level shifting between the input and output happened seamlessly in both directions. It is assembled in a tiny SOT-23-6/SNOC6Z package or come with a bundled circuit. The chip level-shifts logic signals between these two logic levels by taking advantage of the low-capacitance logic gates, configured with gates for the input and output voltage levels. The two power supplies are configured in the proper order, so that the output voltage range is within the input voltage range.

The working principle of the LTC4300-2IMS8#PBF is based on its tiny package size, specialized circuitry, and low capacitance gate technology. The LTC4300-2IMS8#PBF takes advantage of its standard logic gates, with two for the input and output voltage levels, and two for the power supply connections. This configuration allows the LTC4300-2IMS8#PBF to level shift the input and output logic signals in both directions seamlessly, over the wide voltage range, with no crossover distortion or noise spikes.

The capacitive gate technology used by the LTC4300-2IMS8#PBF facilitates level-shifting between input and output signals by employing two low capacitance logic gates, one for the input signal, and one for the output signal. The input signal and output signal pass through each of these gates, allowing the level of the signal to be shifted between the input and output voltage ranges. The LTC4300-2IMS8#PBF also features a low RON of 20Ω, which helps to control ringing and other structure-borne noise issues that commonly arise in level shifting applications.

One potential application of the LTC4300-2IMS8#PBF is for connecting between different logic families. The logic families such as I2C, SPI, UART, USB, and LIN are commonly used in different device types, and the LTC4300-2IMS8#PBF can be used to connect the different logic families without any crossover distortion or noise spikes. It can also be used to connect devices operating at different voltage levels, to allow them to communicate with each other. This could be useful when connecting different types of controllers, CPUs, or ICs.

The LTC4300-2IMS8#PBF is a field-proven level shifter IC, offering robust level shifting capabilities in a tiny package. It has a wide input and output voltage range, low RON of 20Ω, and capacitive gate technology, allowing for seamless level shifting without distortion or noise. Its potential applications are in connecting different logic families, or in connecting different devices operating at different voltage levels. It can be used in automotive, consumer, industrial and medical applications.
