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 complementary G and G inputs. Each control input PIN CONNECTION (top view) HC7240 HC7241 HC7244 governs four BUS BUFFERs. The HC7240, HC7241 and HC7244 have the same pin configuration and function as the HC240, 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.
