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
