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
