Working Principles

The 74LCX244MTCX_E4 operates by receiving input signals through its bidirectional inputs (A1-A6 and B1-B4) and transmitting them to the corresponding outputs (I/O1-I/O7). The direction of data flow is controlled by the Output Enable (OE#) pin. When OE# is low, the IC is enabled, allowing data to pass from inputs to outputs. Conversely, when OE# is high, the IC is disabled, isolating the inputs from the outputs.
