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.

The designer of M74HC241 has a choise of select combination of inverting and non-inverting outputs, symmetrical G (active low output control) input, and 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.
