M54HC42 M74HC42 . HIGH SPEED tPD = 13 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 10 LSTTL LOADS . SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 4 mA (MIN.) . BALANCED PROPAGATION DELAYS tPLH = tPHL . WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V . PIN AND FUNCTION COMPATIBLE WITH 54/74LS42 DESCRIPTION The M54/74HC42 is a high speed CMOS BCD-TODECIMAL DECODER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. A BCD code applied to the four inputs A-D selects one of ten decimal outputs Y0-Y9, which goes low to fifteen gives a high level at all outputs.
