The LTC1555LEGN-1.8#TRPBF is a device classified under Logic-Translators and Level Shifters. It is made by Linear Technology or LT, and is primarily used to transmit analog data between two systems that run on different voltage supplies. This type of chip is also capable of producing very precise voltage levels and can be used to check digital signals coming from two sources, and at the same time, it is also able to condition them.

The LTC1555LEGN-1.8#TRPBF is an ideal choice for designers in applications which need to interface between two systems, one running on a low voltage supply and the other needing a voltage supply of at least 1.8V. It is an easy single chip solution that requires very low power in order to operate. This energy-efficient device is also ideal for use in USB applications, such as USB peripherals, as it can efficiently regulate the 5V logic and 0.4V back-bias logic levels.

The LTC1555LEGN-1.8#TRPBF operates with two threshold levels; the high voltage level is set at the LVCMOS (Low Voltage CMOS) voltage and the low voltage level is set at 0.4V. The device employs the concept of level shifting in order to be able to translate data between the two integration points. This architecture is also responsible for providing a precise output voltage level, regardless of the input voltage VCC level.

The mechanism by which this chip is able to perform level shifting is fairly straightforward. When there is no signal input center, it sets a known reference voltage against ground, thereby allowing the other connected device to determine the state of the signal. In the event that there is a signal input center and the input voltage is below the LVCMOS threshold, then the reference voltage is adjusted accordingly. This signal is then passed on to the receiver and it is tailored to the voltage ranges of the device which it is being sent to.

The LTC1555LEGN-1.8#TRPBF performs this operation using its N-channel MOSFETs which are used as voltage level-shifting switches. During operation, these switches are periodically opened and closed and the timing of this action is determined by the level-shifting voltage. When there is no input signal, then the MOSFETs remain open and there is no change in the output voltage level, thus providing a constant reference source for the receiver device to detect the incoming data.

This device also comes equipped with three other components which include a frequency-compensated amplifier, a digital regulated output-discharge circuit, and a logic level shift enable. The frequency-compensated amplifier is responsible for maintaining stable voltage levels along the circuit when exposed to external noise, while the output-discharge circuit is used to quickly discharge exiting capacitance, ensuring that the voltage levels remain consistent when the circuit is off. The logic level shift enable is also used to enable or disable the device depending on the input received.

The LTC1555LEGN-1.8#TRPBF is an excellent choice for designers and engineers who need to interface between two systems that operate on different voltage supplies. It is a simple yet effective solution which can quickly regulate the voltage levels and thus make sure the two systems receive the same signal without any loss of accuracy. Additionally, it is a very energy-efficient device and does not consume too much power, making it ideal for use in various USB applications.
