DESCRIPTION

The M54/74HCT257 and the M54/74HCT258 are high speed CMOS MULTIPLEXERs fabricated with silicon gate C2MOS technology.

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

■ HIGH SPEED tPD = 16 ns (TYP.) at VCC = 5 V

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

■ COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE IOH = IOL = 6 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

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