DESCRIPTION

TheM54/74HC7240, HC7241andHC7244arehigh
speed CMOSOCTAL BUS BUFFERsfabricated in
silicongate C2MOS technology.

They have the same high speed performance of
LSTTL combined with true CMOS low power
consumption.

The designerhas a choise of select combination of
inverting and non-inverting outputs, symmetricalG
(active low output control) input, and
complementary G andG inputs. Each controlinput

governsfour BUS BUFFERs.
The HC7240,HC7241 and HC7244 have the same

pinconfigurationandfunctionastheHC240,HC241
and HC244 and they have a hysteresis
characteristics with each input so can be used as a
line receiver, etc.

All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
