DESCRIPTION
The designer has a choise of select combination of inverting and non-inverting outputs, symmetrical G (active low output control) input, and PIN CONNECTION (top view) HC240 HC241 HC244 . . . . . . . . B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HCXXXF1R M74HCXXXM1R M74HCXXXB1R M74HCXXXC1R 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.
