DESCRIPTION

The M54/74HC257 and the M54/74HC258 are high speed CMOS MULTIPLEXERs fabricated with silicon gate C2MOS technology.

They have the same high speed performance ofLSTTL combined with true CMOS low power consumption.

■ HIGH SPEED tPD = 10 ns (TYP.) at VCC = 5 V

■ LOW POWER DISSIPATION ICC = 4 µA (MAX.) at TA = 25 °C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 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) = 2 V to 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS257/258
