DESCRIPTION
The M54/74HC240, HC241 and HC244 are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C2MOS technology.
■ HIGH SPEED tPD = 10 ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION ICC = 4 µA (MAX.) at TA = 25 °C
■ 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
