HIGH SPEED tPD = 10 ns (TYP.) at VCC =5V . LOW POWER DISSIPATION ICC =4 µA (MAX.) at TA =25 oC . HIGH NOISE IMMUNITY VNIH =VINL =28 % VCC (MIN.) . OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH|= IOL = 6 mA (MIN) . BALANCED PROPAGATION DELAYS tPLH =tPHL . WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2V to 6V . PIN AND FUNCTION COMPATIBLE WITH 54/74LS240/241/244 DESCRIPTION The M54/74HC240, HC241 and HC244 are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C 2MOS technology. 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 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.
