74HC240 Overview
The ’HC240 and ’HCT240 are inverting three-state buffers having two active-low output enables. The CD74HC241, ’HCT241, ’HC244 and ’HCT244 are non-inverting three-state buffers that differ only in that the 241 has one active-high and one active-low output enable, and the 244 has two active-low output enables. All three types have identical pinouts.
