Description

The'HC240and'HCT240 are inverting three-state buffers having two active-low output enables.The CD74HC241,'HCT241,'HC244and'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.
