The PI4ULS3V304ZMEX is an all-digital, low-voltage differential signaling (LVDS) level shifter device that allows a 1.8V interface to be connected to a 3V3 interface. The device provides a single non-inverting output at the 3V3 interface with selectable input levels of 1.35 V and 1.8 V. It is ideal for applications requiring signal level discrepancy between two components that typically share different voltage levels. This device is part of a family of Logic - Translators, Level Shifters.

The PI4ULS3V304ZMEX is housed in a 7-pin H-LGA package which has an industry standard pin-out. This makes it ideal for use in a variety of circuits, including bus expansion, peripheral interconnects and bridge logic. The device integrates a fast-controlled logic circuit and an adjustable voltage sense circuit to shift logic levels from 1.8V to 3.3V.

The PI4ULS3V304ZMEX has an input high reference threshold of 1.35V and an input low reference threshold of 0.80V. It also features a maximum data rate of 250 Mbits/s and a supply voltage range of 0.8V to 3.6V. This ensures that signals sent between two different voltage levels are transmitted reliably. The output signal can be DC or AC coupled, making it suitable for applications such as memory expansion, data transfers and signal level conversions.

The PI4ULS3V304ZMEX features a level shifter operating in a two-wire configuration. It is designed to translate signals between two voltage levels such as 1.8V and 3.3V. The device shifts the incoming 1.35V signal at the 1.8V interface to the voltage level at the 3.3V interface. The output level is set by an internal voltage reference and can be adjusted from 1.35V to 3.3V. This ensures reliable signal transmission even with the different voltage levels.

The PI4ULS3V304ZMEX works by comparing the input data signal to the internal reference voltage. If the input voltage is greater than the reference voltage, the output will be set to the high level. Conversely, if the input voltage is lower than the reference voltage, the output will be set to the low level. This allows signals with different levels to be transmitted between two components, which typically operate at different voltage levels.

The PI4ULS3V304ZMEX also features a selectable input clock rate, ranging from 0 to 250 MHz, allowing it to be used in applications requiring higher-speed data transfer. The device also has an adjustable output drive strength, which can be adjusted depending on the application. This ensures the correct level of signal integrity is maintained.

The PI4ULS3V304ZMEX is a feature-packed device that is ideal for applications requiring reliable level shifting from one voltage level to another. Its adjustable reference voltage and selectable clock rate makes it suitable for fast data transmissions over long distances. This coupled with its reliability and low power consumption makes it an ideal choice for a variety of applications.
