Logic translators and level shifters are integrated circuits for transforming signals between two logic families. Signals from one family of logic can be sent to the other family with the help of such ICs. The SN65ELT23DGK IC from Texas Instruments is one such IC. It is a dual flexible supply level translator/bus switch with 2-inputs, 3-outputs and I2C-bus super speed (3.4Mbps) support. It is an ideal choice for embedded and portable applications due to its low quiescent current.

In terms of applications, the SN65ELT23DGK is a bus switch usually used in applications that require data to be transferred between two buses that support different logic levels. For instance, it can be used to connect a microcontroller-level logic level to a high-speed application processor. It also proves to be useful in bridging legacy and newer systems. It is designed to excecute data transfers between 1.8V, 1.5V, and 2.5V buses.

In terms of working principle, the SN65ELT23DGK uses an internally controlled slew-rate control technique to reduce system power consumption by reducing the amount of charge injected when interfacing from low voltage to high voltage. It does this by controlling the slew-rate of the signal to a minimum value. It also has an overridePins which can be used to lock out additional recording of data into the register. The SN65ELT23DGK has integrated ESD protection for up to 11kV HBM to provide maximum protection against ESD.

In conclusion, the SN65ELT23DGK from Texas Instruments is a dual flexible supply level translator/bus switch with 2-inputs, 3-outputs and I2C-bus super speed (3.4Mbps) support. It is designed to excecute data transfers between 1.8V, 1.5V, and 2.5V buses. It utilizes an internally controlled slew-rate control technique to reduce system power consumption. It also has an overridePins which can be used to lock out additional recording of data into the register. The SN65ELT23DGK is an ideal choice for embedded and portable applications due to its low quiescent current. It is usually used in applications that require data to be transferred between two buses that support different logic levels.
