Working Principles

The MM74HC240MTC operates based on CMOS technology, which utilizes both NMOS and PMOS transistors to achieve high-speed performance and low power consumption. It functions as a buffer/driver by taking the input signals and providing non-inverted outputs with increased current drive capability. The device is controlled by the OE1 and OE2 pins, which enable or disable the outputs. When disabled, the outputs are in a high-impedance state, allowing multiple devices to be connected together without causing bus contention.
