DESCRIPTION

The 74HC4514 and the 74HC4515 are high speed CMOS 4-LINE TO 16-LINE DECODERS WITH LATCHED INPUTS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption.

. HIGH SPEED tPD = 18 ns (TYP.) AT VCC = 5 V

. LOW POWER DISSIPATION ICC = 4 ?A (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 WITH4514B/4515B
