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.
