Working Principles

The MC74LCX07DR2G is a hex buffer with open drain outputs. It operates as a non-inverting logic gate, meaning that the output signal follows the input signal without any inversion. The open drain outputs allow for flexible connection to other devices by providing either a low impedance path to ground or a high impedance state.

When the input signal is high, the corresponding output is in a high impedance state, effectively disconnecting it from the circuit. When the input signal is low, the output is pulled low, creating a low impedance path to ground. This configuration allows for wired-OR and wired-AND connections, making it suitable for bus-oriented applications.
