Working Principles

The MM74HCT240SJX is based on HCT (High-Speed CMOS Technology). It functions as a non-inverting buffer/driver, which means it amplifies and drives digital signals without changing their logic level. The inputs (A1-A6, B1-B5) are buffered and then transmitted to the corresponding outputs (Y1-Y6) when the output enable (OE) pin is active. The device operates within a specified supply voltage range and is compatible with both TTL and CMOS logic levels.
