Logic-translators, also referred to as level shifters, are digital devices used to translate an input signal from one logic family to another, such as from CMOS to TTL. The SY100ELT982KG, for example, is a translater designed for level shifting and signal translation between the TTL and the 1.8V and 2.5V CMOS logic. It supports TTL voltage levels on both inputs and outputs and is used to drive 1.8V and 2.5V CMOS devices.

The SY100ELT982KG is characterized by low quiescent supply currents, fast switching speed, input buffer hysteresis, bus-hold circuit on inputs, two-stage output driver, and symmetrical active pull-up or pull-down outputs.

The input buffer of the SY100ELT982KG can handle up to +3.6V and offers a low voltage (<0.8V) logic High level. The input buffer hysteresis is 0.6V typical and enables reliable operation even with heavily skewing input signals.

The output drivers have active pull-up or pull-down outputs, allowing for full-speed switching for the most of the loads within the given supply voltage range. Also, the SY100ELT982KG output withstands up to 5.5V.

The application field of the SY100ELT982KG is quite high, given the device\'s wide range of available logic levels and its high-speed operation. The input compatibility with TTL and CMOS logic makes it suitable for connecting a variety of logic families. Aside from external bus translation, the SY100ELT982KG can also be used in general purpose conversions, system-level drives, level translation, buffer gate, and level shifting applications.

The logic translator\'s working principle is straightforward. The logic-level of the input is converted into the level of the target logic and then outputted. This is achieved by the combination of a series of transistors, whose behavior is governed by the source of the input voltage and its current. When the voltage on the source is higher than the specified threshold, it acts as a "switch" that allows current to pass through, and when the voltage is below the threshold, it acts as an "iso-on" that blocks the flow of current.

The SY100ELT982KG is a type of logic translator, or level shifter, designed to convert an input signal from one logic family to another. It has a wide range of compatible logic levels and is characterized by low quiescent supply currents, fast switching speed, input buffer hysteresis, bus-hold circuit on inputs, two-stage output driver, and symmetrical active pull-up or pull-down outputs, making it suitable for connecting a variety of logic families and input sources. The device\'s working principle relies on the combination of transistors, governed by the source of the input voltage, to convert the input signal into the desired voltage level.
