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 C2MOS 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 PIN CONNECTION (top view) HC240 HC241 HC244 . . . . . . . .

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.
