Description

The ’HC240 and ’HCT240 are inverting three-state buffershaving two active-low output enables. The CD74HC240E ,’HCT241, ’HC244 and ’HCT244 are non-inverting threestatebuffers that differ only in that the 241 has one activehighand one active-low output enable, and the 244 has twoactive-low output enables. All three types have identicalpinouts.
