DESCRIPTION
The M54/74HC240, HC241 and HC244 are high
speed CMOS OCTAL BUS BUFFERs fabricated in
silicon gate C2MOS technology.
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.
They have the same high speed performance of
LSTTL combined with true CMOS low power
consumption.
The designer has a choise of select combination of
inverting and non-inverting outputs, symmetrical G
(active low output
control) input, and
