FEATURES
Octal bus interface
Open collector versions of 74F240, 74F241 and 74F244
DESCRIPTION
The 74F756, 74F757 and 74F760 are octal buffers that are ideal for
driving bus lines of buffer memory address registers. The 74F756 is
the open collector version of 74F240, 74F757 is the open collector
version of 74F241 and 74760 is the open collector version of
74F244. These devices feature two Output Enables. OEa and OEb
(or OEb for the 74F757), each controlling four of the outputs.
