Working Principle of MC74LCX541DTR2G

MC74LCX541DTR2G operates on an advanced triple-stage low-voltage CMOS technology, which provides superior noise immunity and high speed switching. The device operates on an identical logic scheme with the traditional Multi-gate CMOS logic family. It uses the complementary logic where one side of each gate is inverted in comparison with its other side to ensure stable operation. For example, the inputs are in the form of A and A′, B and B′ and similarly so for the outputs.

The device has three-state outputs that have direct control from the input signals. These outputs have internal pull-up and pull-down resistors. The pull-up state is provided with a voltage level of VG and pull-down provides a voltage level of VSS. When the output enable is disabled, the outputs are in the high impedance state, thus avoiding any current levels on the outputs. With the enable signal enabled, the voltage levels of pull-up and pull-down is applied to the output accordingly. The enable also allows control of group of outputs with a single control input.
