Working Principles

SN74HC640PWT operates by receiving input signals through its A1 to B5 pins and transmitting them to the corresponding Y1 to Y4 pins. The enable input (OE#) controls the direction of data flow. When OE# is low, the IC functions as a bus transmitter, allowing data to be transmitted from the A inputs to the Y outputs. Conversely, when OE# is high, the IC operates as a bus receiver, enabling data to be received from the B inputs and outputted through the Y outputs.
