DESCRIPTION
The M54/74HC593 is a high speed CMOS 8 BIT REGISTER COUNTER (3 STATE) fabricated with silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

■ HIGH SPEED fMAX = 80 MHz (TYP.) AT VCC = 5 V
■ LOW POWER DISSIPATION ICC = 4 µA (MAX.) AT TA = 25 °C
■ OUTPUT DRIVE CAPABILITY
    10 LSTTL LOADS FOR RCO
    15 LSTTL LOADS FOR Qn
■ BALANCED PROPAGATION DELAYS tPLH = tPHL
■ SYMMETRICAL OUTPUT IMPEDANCE
    IOL = |IOH| = 6 mA (MIN.) for Qn
    IOL = |IOH| = 4 mA (MIN.) for RCO
■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 % VCC (MIN.)
■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V
■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS593
