MC100ELT24DTR2G is a logic device used to shift logic levels between two voltages. It can also be used to translate between logic families, such as a logical input signal from an NPL circuit to an LVCMOS compatible signal. The device is bipolar, operating at two different supply voltages, one for the input and one for the output.

The device is designed for many applications, some of which include bus interface, bus driver, bus repeater, and translator applications. The advantage of the MC100ELT24DTR2G is that it is capable of shifting between the different logic families and maintaining high data rates and low static power dissipation. It also has an excellent jitter performance.

The MC100ELT24DTR2G has two differential inputs, two differential outputs and two supply rails. The differential inputs are LVDS compatible and can be driven from TTL or LVCMOS inputs. The differential outputs are designed to output a voltage level compatible with TTL or LVCMOS. The two supply rails can be either 5V or 3.3V giving the device versatile power options.

The operating principle of the device can be things down to two main points: First, when an input signal is received, the two differential outputs will always be in opposite logic states. This ensures that any negotiation between logic families is correctly done. Secondly, depending on the voltage levels of the supply rails, the outputs will either output a high or low logic level.

Using the supplied example applications, it is possible to use the device as a level shifter between two power domains. The power domain of the inputs should be set up to match the input logic family and the power domain of the outputs should be set up to match the output logic family. Suppose an input signal is in an LVCMOS format and wants to be level shifted to an LVDS compatible format. The 5V power domain should be used for the inputs and the 3.3V power domain should be used for the outputs. As the inputs receive signals, the 5V power domain will create a high logic level and the 3.3V power domain will create a low logic level, hence shifting the logic level.

The MC100ELT24DTR2G is an excellent logic device for logic-family translations and level shifting applications. By providing two power rails and maintaining excellent data rates and jitter performance, the device efficiently translates different logic families and shifts between the different power domains. It is the perfect choice for applications where different logic families need to be negotiable and selected, or significantly different power domains need to be bridged.
