The FXLA104UMX is a high performance, single channel ESD/latch-up protected CMOS level translator. It allows a high-voltage and a low-voltage interface to be connected together in a wide variety of logic families and voltage levels. The FXLA104UMX is designed to easily integrate into high-speed systems and provide a low-skew, low-glitch design. It enables bidirectional data transfer between multi-voltage devices, where one side is powered with a higher voltage than the other side.

The main application fields of the FXLA104UMX are a wide variety of interface applications, from interfacing between different voltage families to interfacing between multiple host processors. In addition, the device also serves as an interface between high-speed and low-speed logic families in a wide variety of designs.

The FXLA104UMX has an extended 2.2 to 5.5V operating range, and it can be used to interface with various combinations of logic families and voltage levels, including LVTTL, LVCMOS and HSTL, as well as for point-to-point systems up to 2.5V and 5V systems up to 3.3V. The device is designed to improve electromigration (EMC) noise immunity and latch-up protection.

The FXLA104UMX device operates with a single supply voltage, usually connected to Vcc. It uses two digital control signals, EN and SLP, to generate a mulit-translational input/output voltage level. When EN is set to a low, the output is in a low power-down state and no data is allowed to pass through. When EN is set to a high, the output will follow the device input voltage level. The SLP signal is used to select the input\'s logic level, and it is provided for flexibility when interfacing with different logic levels.

When the device is enabled (EN = 1) and its input voltage is below the threshold value as defined by the SLP signal, the device will output a high level. Conversely, when the input voltage is above the threshold value, the device will output a low logical level. It is possible to preset the level of the SLP signal before data transmission, allowing the FXLA104UMX to interface easily with different logic families. This ensures that the device can easily interface with multi-voltage designs.

In summary, the FXLA104UMX is a high performance, single channel ESD/latch-up protected CMOS level translator that provides bidirectional data transfer between multi-voltage devices. The device provides an extended 2.2 to 5.5V operating range and has two digital control signals, EN and SLP, to generate a multi-translational input/output voltage level. The FXLA104UMX is an ideal device for interfacing between different logic families and voltage levels and for point-to-point systems.
