DESCRIPTION

The 74HC154 is a high speed CMOS 4 TO 16-LINE DECODER/DEMULTIPLEXER fabricated in silicon gate C2MOS technology. It has the same high speed performance ofLSTTL combined with true CMOS low power consumption.

■ HIGH SPEED

■ tPD = 15 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 = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V to 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS154
