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.

NOTE: When ordering, use the entire part number. The suffixes 96
and R denote tape and reel. The suffix T denotes a small-quantity
reel of 250.
CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
