Working Principle

The GTL2008PW takes the input logic signals from one logic family and translate them into an output for a different logic family. It can detect the input logic family and adapt the output levels to the corresponding output logic family. The GTL2008PW also supports a low-current input option to allow for the lower input current level of some logic families. The GTL2008PW is also able to independently source and sink current with its 16mA capability while keeping the current to both sources and sinks identical.

The GTL2008PW consists of internal control logic, level shifters, differential amplifiers and analog and digital filters. The device drives the output of one logic family to the input of the other logic family and provides the proper output voltage levels. The device can either convert the output voltage level when switching from one level to another, or maintain a continuous output voltage level.

The GTL2008PW provides differential drive capability which can provide a controlled voltage transition from one logic family to another without any offset. The device also provides logic hysteresis which allows the device to reject noise signals and maintain a consistent output voltage for each logic family.
