Description
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.
