DESCRIPTION
The M54/74HC240, HC241 and HC244 are high
speed CMOS OCTAL BUS BUFFERs fabricated in
silicon gate C²MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power
consumption.
complementary G and G inputs. Each control input
governs four BUS BUFFERs.
These devices are designed to be used with 3 state
memory address drivers, etc. All inputs are
equipped with protection circuits against static
discharge and transient excess voltage.
The designer has a choise of select combination of
inverting and non-inverting outputs, symmetrical G
(active low output control) input, and
